A proof of the Continuum Hypothesis as originally posed by Georg Cantor in 1878; that an uncountable set of real numbers has the same cardinality as the set of all real numbers. Any set of real numbers can be encoded by the infinite paths of a binary tree. If the binary tree has an uncountable node it must have a descendant with 2 uncountable successors. Each of those will have descendants with 2 uncountable successors, recursively. As a result the infinite paths of an uncountable binary tree will have the same cardinality as the set of all real numbers, as will the uncountable set of real numbers encoded by the tree.

The EF-axiom describes the Efremovifč proximity δ by V.A. Efremovič from 1934 and published in Russian in 1951. We interpret the operator δ to mean "nearby" or "in proximity". The size of an antecedent or consequent is not stated for the operator, so we determine that the operator applies to unrelated literals as as ((A∈ B) Nor (B∈ A)). The proof result is for 256-values because four theorems are evaluated as variables. We find the EF-axiom is not tautologous. The implications to topology are legion.

We evaluate higher-order logic based on the principle of mathematical induction. Meth8/VŁ4 treats sets and variables as variables. The quantification over quantification is not bivalent.
We alleviate this constraining condition by distributing the quantified expression over nested expressions. At each nested level, the quantification is explicitly distributed for clarity. We conclude that higher-order logic is not bivalent and that nested quantification is better expressed as explicitly distributed.

We evaluate prenex normal form of quantifier presentation on rules for the connectives of conjunction, disjunction, implication, and for negation. The format is not tautologous, not bivalent, and hence refuted. What follows is that many theorems produced with prenex for computer science, mathematics, and physics are now suspicious. A notable example is the satisfiability algorithms produced by Martin Davis and Hilary Putnam which are now mistaken.

This refutes Tarski's theorem for the undefinability of truth as:
"no definable and sound extension of Peano Arithmetic can be complete"; or in abstract terms,
"the proof of a system cannot be demonstrated by itself".
Tarski's theorem is an arguable equivalent to Godel's incompleteness theorem, as based on the liar's paradox.
[Remark added later:
Tarski's theorem as used since about 1936 is an underpinning of quantum theory and a universal justification for atheism.]

**Comments:** 2 Pages. Papers by and relating to Florentin Smaradnache span many areas at viXra, but the appropriate field is Set Theory and Logic. Many of them are translated as crude ruse to garner publicity. The study neutrosohic logic is mostly specious.

We evaluate the neutrosophic logic based on its most atomic level of soft latices, as published by Springer-Verlag in 2016.
We refute the theorem "Every neutrosophic soft lattice is a one-sided distributive neutrosophic soft lattice."
This brief evaluation implies that the field of soft set theory as originally introduced by D. Molodtsov is suspicious and specifically that the field of neutrosophic logic, as evidenced in its basis of soft set theory, is unworkable.
This conclusion is multitudinal because of the plethora of duplicated papers as translations in multiple fields at vixra.org regarding the neutrosophic logic system of Florentin Smarandache.

Alan Turing's difficulty was in expressing the halting problem in the format of a two-valued logic which was not as expressive as in a four-valued logic to show nuances of what exactly the equation stated.
In comparison to Gödel's incompleteness theorems, Turing's halting problem has no superficial similarities other than being refuted as not a problem. Hence in contrast, both expressions are disparate and ultimately unrelated as to content meaning.
Therefore: The assumption that there is a consistent and complete axiomatization of all true first-order logic statements about natural numbers must be tautologous.

The critical analysis of the foundation of set theory is proposed. The unity of formal logic and rational dialectics is the correct methodological basis of the analysis. The analysis leads to the following results: (1) the mathematical concept of set should be analyzed on the basis of the formal-logical clauses “Definition of concept”, “Logical class”, “Division of concept”, “Basis of division”, “Rules of division”; (2) the standard mathematical theory of sets is an erroneous theory because it does not contain definition of the concept “element (object) of set”; (3) the concept of empty set (class) is a meaningless, erroneous, and inadmissible one because the definition of the concept “empty set (class)” contradicts to the definition of the logical class. (If the set (class) does not contain a single element (object), then there is no feature (sign) of the element (object). This implies that the concept of empty set (class) has no content and volume (scope). Therefore, this concept is inadmissible one); (4) the standard mathematical operations of union, intersection and difference of sets (classes) are meaningless, erroneous and inadmissible operations because they do not satisfy the following formal-logical condition: every separate element (object) of the set (class) must be in only one some set (class) and cannot be in two sets (classes). Thus, the results of formal-logical analysis prove that the standard mathematical theory of sets is an erroneous theory because it does not satisfy the criterion of truth.

Pythagorean fuzzy set (PFS) initially extended by Yager from intuitionistic fuzzy set (IFS), which can model uncertain information with more general conditions in the process of multi-criteria decision making (MCDM). The fuzzy decision analysis of this paper is mainly based on
two expressions in Pythagorean fuzzy environment, namely, Pythagorean fuzzy number (PFN) and interval-valued Pythagorean fuzzy number (IVPFN). We initiate a novel axiomatic definition of Pythagorean fuzzy distance measure, including PFNs and IVPFNs, and put forward the corresponding theorems and prove them. Based on the defined distance measures, the closeness indexes are developed for PFNs and IVPFNs inspired by the idea of technique for order preference by similarity to ideal solution (TOPSIS) approach. After these basic definitions have been established, the
hierarchical decision approach is presented to handle MCDM problems under Pythagorean fuzzy environment. To address hierarchical decision issues, the closeness index-based score function is defined to calculate the score of each permutation for the optimal alternative. To determine criterion weights, a new method based on the proposed similarity measure and aggregation operator of PFNs and IVPFNs is presented according to Pythagorean fuzzy information from decision
matrix, rather than being provided in advance by decision makers, which can effectively reduce human subjectivity. An experimental case is conducted to demonstrate the applicability and flexibility of the proposed decision approach. Finally, the extension forms of Pythagorean fuzzy decision approach for heterogeneous information are briefly introduced as the further application in other uncertain information processing fields.

The rationale for rendering quantifiers as modal operators in Meth8 has arguments from satisfiability and reproducability of invalidating and validating syllogisms.
The Square of Opposition (original) produced four combinations for each corner A, I, E, O for 4 ^ 4 = 256 syllogisms. Medieval scholars determined 24 of the 256 syllogisms were valid deductions. Of those, 9 were made valid but only after additional known assumptions were applied as fix ups. Meth8 Tautologous none of the 24 syllogisms before fix ups. Meth8 also discovered correct additional assumptions to render the other 15 syllogisms Tautologous. We use Meth8 to replicate the 24 valid syllogisms derived from the original Square of Opposition. In the process we make three recent advances.
1. A third assumption is needed to fix up Modus Cesare EAE-2
2. The third assumption cannot be removed from Modus Camestros AEO-2 (as in other syllogisms with known third assumptions); and
3. No third assumptions are required for the other 22 syllogisms.

The modern revision of the square of opposition is not validated as tautologous by the Meth8 logic model checker, as based on system variant VŁ4. Consequently we redefine the square so that it is validated as true my Meth8. Instead of definientia using implication for universal terms or conjunction for existential terms, we adopt the equivalent connective for all terms. The modal modifiers necessity and possibility map quantifiers as applying to the entire terms rather than to the antecedent within the terms. We note the validating connectives for the edges on the square are: \ Nand for the Contraries and Contradictories; > Imply for the Subalterns; and + Or for the Subcontraries.

The modern, revised square of opposition is not validated as tautologous by the Meth8 logic checker in five models for all expressions. This leads us to consider that any logic system based on the square of opposition is spurious. What follows then is that a first order predicate logic based on the square of opposition is now suspicious.

The Gödel incompleteness theorem states in effect that sequences of logic symbols can be assigned to strings of natural numbers, but because it is assumed there are more natural number than sequences of logic symbols, the symbols are incomplete as a self-referencing mechanism to describe repeatedly themselves as yet more numbers. (The Gödel completeness theorem states in effect that the sequences of logic symbols may be consistent to form a logic system that is sufficiently complete enough to prove theorems as tautology.)
The arguments ultimately turn on the mapping of sequences of symbols into strings of natural numbers.
The arguments also assume a function to map numbers as a domain into symbols as an image in a co-domain, also collectively named a range. The incompleteness theorem is that such a function exists and operates where all of its domain is larger than the smaller image existing within all of the co-domain. The completeness theorem is that all of the image, existing solely for its purposes, is self-sufficient unto the existence of itself.
We are interested in mapping the image in the co-domain as sequences of logic symbols back into the originating domain which is named a preimage. Attempting such an inverse function is not allowed by the one-way definition of a function to an image as dictated by the incompleteness theorem. We show this invertive approach or reverse process is not tautologous by evaluating the misuse of the application of quantified operators in the one-way functional mapping in the first place.
Our experimental results in mapping are the definitive evidence that constructionist logic and subsequently constructivistic logics are not complete (deny the completeness theorem) and hence deny the incompleteness theorem. The most important evidence is that those logics can exist only by ignoring the law of excluded middle (LEM) that "p or not p is a tautology", (p+~p)=(p=p). We argue that any system denying the LEM is not tautologous and hence unworkable.

1. The axiom or rule of necessitation N states that if p is a theorem, then necessarily p is a theorem: If ⊢ p then ⊢ ◻p.
We show this is non-contingent (a truth), but not tautologous (a proof). We evaluate axioms (in bold) of N, K, T, 4, B, D, 5 to derive systems (in italics) of K, M, T, S4, S5, D.
We conclude that N the axiom or rule of necessitation is not tautologous Because system M as derived and rendered is not tautologous, system G-M also not tautologous.
What follows is that systems derived from using M are tainted, regardless of the tautological status of the result so masking the defect, such as systems S4, B, and S5.
We also find that Gentzen-sequent proof is suspicious, perhaps due to its non bi-valent lattice basis in a vector space.

In applied and theoretical mathematics, assertions are categorized in alphabetical order as: axiom; conjecture; definition, entry; equation; expression; formula; functor; hypothesis; inequality; metatheorem; paradox; problem; proof; schema; system; theorem; and thesis. We evaluate 130 objects for 519 assertions to validate 156 as tautology and 363 as not (70%). We use Meth8 that is a modal logic checker in five models.
The semantic content or predicate basis of some expressions on their face does not disqualify them from evaluation by Meth8 in classical modal logic. However, the rules of classical logic, as based on the corrected Square of Opposition by Meth8, apply to virtually any logic system. Consequently some numerical equations are mapped to classical logic as Meth8 scripts.
The rationale for mapping quantifiers as modal operators is in the Appendix based on satisfiability and reproducability of validation of syllogisms.
A table lists what was tested with separated results. The names are numbered in alphabetical order. Test results are Invalidated as Not Validated Tautology (nvt) or Validated as Tautology (vt). For a paradox, invalidated means it is not validated as true, that is, it is not a paradox or contradiction.
The experimental tests used variables for 4 propositions, 4 theorems, and 11 propositions. The size of truth tables are respectively for 16-, 256-, and 2048- truth values. One formula of Popper in 250-characters processed in 125-steps instantly due to recent advances in look up table indexing.
The Meth8 modal theorem prover implements the logic system variant VŁ4 which corrects the quaternary Ł4 of Łukasiewicz. There are two sets of truth values on the 2-tuple {00, 10, 01, 11} as respectively

Finding whether a boolean formula is a tautology or not in a feasible time is an important problem of computer science. Many algorithms have been developed to solve this problem but none of them is a polynomial time algorithm. Our aim is
to develop an algorithm that achieve this in polynomial time.
In this article, we convert boolean functions to some graph forms in polynomial time. They are called two dimensional formulas and similar to AND-OR graphs except arches on them are bidirectional. Then these graphs are investigated to find properties which can be used to differentiate tautological formulas from non tautological ones.

The power set contains all possible infinite binary sequences who represent the fraction part of the standard numbers together with the integers for the whole number part. The set of standard numbers includes the rational numbers and forms a field (D, +, *) similar to, yet distinct from the set of real numbers R.

This article adds a new axiom to ZFC that assumes there is a set x which is initially the empty set and thereafter the successor function (S) is instantly applied once in-place to x at each time interval (½ⁿ n>0) in seconds. Next, a very simple question is proposed to ZFC. What is x after one second elapses?
By definition, each time S is applied in-place to x, a new element is inserted into x. So, given that S is applied at each time interval (½ⁿ n>0) then an infinite collection of elements is added to x so, x is countable infinite. On the other hand, since x begins as the empty set and only S is applied to x then x cannot be anything other than a finite natural number. Hence, x is finite. Clearly, in-place counting according to the interval timings (½ⁿ n>0) demonstrates a problem in ZFC

This paper critically examines the Cantor Diagonal Argument (CDA) that is used in
set theory to draw a distinction between the cardinality of the natural numbers and
that of the real numbers. In the absence of a verified English translation of the original
1891 Cantor paper from which it is said to be derived, the CDA is discussed here
using a consensus from the forms found in a range of published sources (from
"popular" to "professional"). Some general comments are made on these sources. The
discussion then focusses on the CDA as applied to the correspondence between the set
of the natural numbers, and the set of real numbers in the open range (0,1) in their
expansion from decimal digits (0.123… etc.).
Four points critical of the CDA are raised: (1) The conventional presentation of the
CDA forms a putative new real number (X) from the "diagonal" of the chosen list of
real numbers and which is therefore not on this initial list; however, it omits to
consider that it may indeed be on the later part of the list, which is never exhausted
however far the "diagonal" list is extended. (2) This aspect, combined with the fact
that X is still composed of decimal digits, that is, it is a real number as defined,
indicates that it must be on the later part of the list, that is, it is not a "new" number at
all. (3) The conventional application of the CDA leads to one putative "new" real
number (X); however, the logical extension of this in its "exhaustive" application, that
is, by using all possible different methods of alteration of the decimal digits on the
"diagonal", and by reordering the list in all possible ways, leads to a list of putative
"new" real numbers that become orders of magnitude longer than the chosen
"diagonal" list. (4) The CDA is apparently considered to be a method that is
applicable generally; however, testing this applicability with the natural numbers
themselves leads to a contradiction.
Following on from this, it is found that it indeed is possible to set up a one-to-one
correspondence between the natural numbers and the real numbers in (0,1), that is, !
⇔ "; this takes the form: … a3 a2 a1 ⇔ 0. a1 a2 a3 …, where the right hand extension
of the natural number is intended to be a mirror image of the left hand extension of
the real number. It is also shown how this may be extended to real numbers outside
the range (0,1).
Additionally, a form of the CDA was presented by Wilfred Hodges in his 1998
critical review of "hopeless papers" dealing with the CDA; this form is also examined
from the same viewpoints, and to the same conclusions.
Finally, some comments are made on the concept of "infinity", pointing out that to
consider this as an entity is a category error, since it simply represents an absence, that
is, the absence of a termination to a process.

Throughout this paper, we are trying to show how and why our Mathematical frame-work seems inappropriate to solve problems in Theory of Computation. More exactly, the concept of turning back in time in paradoxes causes inconsistency in modeling of the concept of Time in some semantic situations. As we see in the first chapter, by introducing a version of “Unexpected Hanging Paradox”, first we attempt to open a new explanation for some paradoxes. In the second step, by applying this paradox, it is demonstrated that any formalized system for the Theory of Computation based on Classical Logic and Turing Model of Computation leads us to a contradiction. We conclude that our mathematical frame work is inappropriate for Theory of Computation. Furthermore, the result provides us a reason that many problems in Complexity Theory resist to be solved.

In the world of transfinite cardinality, any talk of number density, dart-board hits, proportions or probability is just a pouring from the empty into the void. Transfinite cardinality is unrelated to any normal concept of proportion or density over an interval and no understanding of it can obtained from probabilistic analogies. This is demonstrated by comparing extremely sparse and extremely dense collections of reals which are normally understood as uncountable and countable respectively. Should this incline one to think that Cantor’s equivalence definition is inappropriate for identifying the “size” of an infinite collection ?

Many have suggested that the infinite set has a fundamental problem. The usual complaint rails against the actually infinite which (to critics of various finitist persuasions) unjustifiably goes beyond the finite. Here we observe the exact opposite. The problem of the infinite set defined to have an identity (content) that is specified and restricted to be forever finite .
Set theory is taken at its word. The existence of the infinite set and the representation of irrational reals as infinite sets of terms is accepted. In this context, it is shown that the standard definition of the infinite countable set is inconsistent with the existence of its own classic convergents of construction. If the set is infinite then it must be quite unlike that which set theory asserts it to be.
Set theory found itself into some trouble over a century ago trusting an unrestricted anthropic comprehension. But serious doubt is cast on the validity of infinite sets which have been defined by a comprehension which overly-restricts their content.

Unfortunately, Cantor was wrong. His notion of transfinite bijection is flawed. Cantor introduced this notion of transfinite bijection as the additional axiom, even though without even realising this. From this error, other errors sprung into the existence. He did all this in the heroic effort to justify the death of infinitesimals, even though he wasn't aware of this either. Cantor went bravely on to defend the established error in higher mathematics before his mentors and peers who banished infinitesimals. Instead, he demonstrated the error of it. He never realised this as well. This paper elucidates this link between Cantor's errors and infinitesimals.

It is shown that Cantor's diagonal argument fails because either there is no actual infinity and hence no defined diagonal number or there is actual infinity but the diagonal number cannot be distinguished from all real numbers of the Cantor list. Further it is shown by another argument that there are not uncountably many paths in the complete infinite Binary Tree.

The Russell Paradox (1) considers the set, R, of all sets that are not members of themselves. On its surface, it seems like R belongs to itself only if it doesn't belong to itself. This is where the paradox come from. Here, a solution is proposed that is similar to Russell's method based on his theory of types (1,2) but is instead based on the definition of why things exist as described in previous work (3). In that work, it was proposed that a thing exists if it is a grouping defining what is contained within. A corollary is that a thing, such as a set, does not exist until what is contained within is defined. A second corollary is that after a grouping defining what is contained within is present, and the thing exists, if one then alters the definition of what is contained within, the first existent entity is destroyed and a different existent entity is created. Based on this, set R of the Russell Paradox does not even exist until after the list of the elements it contains (e.g. the list of all sets that aren't members of themselves) is defined. Once this list of elements is completely defined, R then springs into existence. Therefore, because it doesn't exist until after its list of elements is defined, R obviously can't be in this list of elements and, thus, cannot be a member of itself; so, the paradox is resolved. Additionally, one can't then put R back into its list of elements after the fact because if this were done, it would be a different list of elements, and it would no longer be the original set R, but some new set. This same type of reasoning is then applied to the Godel Incompleteness Theorem, which roughly states that there will always be some statements within a formal system of arithmetic (system P) that are true but that can't be proven to be true. Briefly, this reasoning suggests that arguments such as the Godel sentence and diagonalization arguments confuse references to future, not yet existent statements with a current and existent statement saying that the future statements are unprovable. Current and existent statements are different existent entities than future, not yet existent statements and should not be conflated. In conclusion, a new resolution of the Russell Paradox and some issues with the Godel Incompleteness Theorem are described.

Here, the conclusion in set theory that the size of an infinite set is the same as the size of an infinite subset derived from it is questioned.This is done not to try and invalidate any mathematical results because mathematics is an abstract field and does not necessarily have to accurately describe the physical world but in order to prompt the reexamination of the use of this result in physics, which does have to accurately describe the real, physical world and the relationships between its components. The rationale is as follows. First, it is suggested that thought experiments are still experiments and should follow the rules for good experimental technique, which include the need to study a system in a setting as close as possible to the "natural setting" to try and avoid experimental artifacts. Now, starting with the single set of the positive integers, one wants to compare the total number of integers to the total number of even integers within the "natural setting" of the single original set. The traditional experimental processing method extracts the even integers, puts them into a separate subset and pairs off the subset's and set's members one-to-one with a function. After doing this, no elements are left over, and, therefore, the original set and the subset extracted from it are said to be the same size. However, extracting the evens and putting them into a separate subset dramatically alters the original single set system. This is analogous to a biologist extracting the nucleus from a cell, studying the nucleus and remaining parts of the cell in isolation and assuming that the results obtained are the same as in the original intact cell. They often are not. Does extracting the even integers out into a subset alter the results compared to those that would be obtained in the natural single set system? Yes. In the single set system, the positive integers march lockstep and in- phase with the odd integers from one to infinity, meaning that there is a built-in relationship in this system of one positive integer for every two total integers, which means that there are only one-half as many positive integers as total integers. This is a different result than that obtained after the subset extraction method, which means that the result produced by this method is an experimental artifact. This should be unacceptable in a well done experiment even if it is a thought experiment. It is suggested that this artifact may be related to some of the problems associated with infinities in physics.

In this paper we present a new neutrosophic crisp family generated from the three components’
neutrosophic crisp sets presented by Salama [4]. The idea behind Salam’s neutrosophic crisp set
was to classify the elements of a universe of discourse with respect to an event ”A” into three
classes: one class contains those elements that are fully supportive to A, another class contains
those elements that totally against A, and a third class for those elements that stand in a distance
from being with or against A. Our aim here is to study the elements of the universe of discourse
which their existence is beyond the three classes of the neutrosophic crisp set given by Salama. By adding more components we will get a four components’ neutrosophic crisp sets called the Ultra Neutrosophic Crisp Sets. Four types of set’s operations is defined and the properties of the new ultra neutrosophic crisp sets are studied. Moreover, a definition of the relation between two ultra neutrosophic crisp sets is given.

Curry's paradox is generally considered to be one of the hardest paradoxes to solve. However, it is shown here that the solution is however trivial and the paradox turns out to be no paradox at all. Reviewing the starting point of the paradox, it is concluded that it amounts to a false definition or assertion and therefore it is to be expected, as opposed to being paradoxical, to arrive to a false conclusion. Despite that fact that verifying the truth value of the first statement of the paradox is trivial, mathematicians and logicians have failed to do so and merely assumed that it is true. Taking this into consideration that it is false, the paradox is however dismissed. This conclusion puts to rest an important paradox that preoccupies logicians and points out the importance of verifying one's assumptions.

According to James R. Meyer, In mathematics, a theorem is intended to be a term for a very precise and definite concept - a theorem is a statement that is proved, using rigorous mathematical reasoning, to follow according to a set of logical rules, from a set of initial statements. These initial statements are usually called axioms, and these are statements that are accepted without being proven. The set of logical rules which determine how one statement can follow from another are usually called the rules of inference . And basically, Gödel's incompleteness theorem is any statement that says that for every formal mathematical system, there are sentences that cannot be proved to be true or false in that system.

Neutrosophic Over-/Under-/Off-Set and -Logic were defined for the first time by Smarandache in 1995 and published in 2007. They are totally different from other sets/logics/probabilities.
He extended the neutrosophic set respectively to Neutrosophic Overset {when some neutrosophic component is > 1}, Neutrosophic Underset {when some neutrosophic component is < 0}, and to Neutrosophic Offset {when some neutrosophic components are off the interval [0, 1], i.e. some neutrosophic component > 1 and other neutrosophic component < 0}.
This is no surprise with respect to the classical fuzzy set/logic, intuitionistic fuzzy set/logic, or classical/imprecise probability, where the values are not allowed outside the interval [0, 1], since our real-world has numerous examples and applications of over-/under-/off-neutrosophic components.

A totally ordered set is identified with cardinality strictly between natural (N) and real (R) numbers. This set, denoted DS, is essentially an experimental finding, identified in unrelated patented research on nonuniform data sampling and self-stabilizing computer arithmetic. Its theoretical validation here will provide concrete proof that the Continuum Hypothesis (CH) is false. Note that this is distinct from determining whether CH can or cannot be proven from current axioms of set theory, which is settled. Also note that the Generalized Continuum Hypothesis is not addressed. First, Cantor diagonalization is applied isomorphically to prove that DS has strictly more than Cardinality(N) points. Then three (3) distinct proofs are provided to show that DS contains strictly fewer than Cardinality(R) elements. Each proof relies on a distinct property of primes. It is surmised that the considerable research efforts to-date on CH missed this result due to over-generalization, by considering all Alephi sets, i=0.., ∞. Those efforts thereby missed the impact of primes specifically on Aleph0/Aleph1 sets.

linguistic variables are hybridization of uncertain linguistic variables and interval neutrosophic sets and they can easily express the imprecise, indeterminate and inconsistent

In this article, starting from primary representation of neutrosophic information, namely the triplet (μ, ω, ν) made up of the degree of truth μ, degree of indeterminacy ω and degree of falsity ν, we define a refined representation in a penta-valued fuzzy space, described by the index of truth t, index of falsity f, index of ignorance u, index of contradiction c and index of hesitation h. In the proposed penta-valued refined representation the indeterminacy was split into three sub-indeterminacies such as ignorance, contradiction and hesitancy. The set of the proposed five indexes represent the similarities of the neutrosophic information (μ, ω, ν) with these particular values: T=(1,0,0), F=(0,0,1), U=(0,0,0), C=(1,0,1) and H=(0.5,1,0.5). This representation can be useful when the neutrosophic information is obtained from bipolar information which is defined by the degree of truth and the degree of falsity to which is added the third parameter, its cumulative degree of imprecision.

In contrast to Church, who proved in 1936, based on papers by Gödel, that a dual decision problem for the conventional axiomatic first-order predicate calculus is unsolvable, I have solved a trial decision problem algebraically (and hence analytically, not tabularily) for a properly designed axiomatic first-order algebraico-predicate calculus, called briefly the trial logic (TL), and have successfully applied the pertinent algebraic decision procedures to all conceivable logical relations of academic or practical interest, including the 19 categorical syllogisms. The structure of the TL is a synthesis of the structure of a conventional axiomatic first-order predicate calculus (briefly CAPC) and of the structure of an abstract integral domain. Accordingly, the TL contains as its autonomous parts the so-called Predicate-Free Relational Trial Logic (PFRTL), which is parallel to a conventional axiomatic sentential calculus (CASC), and the so-called Binder-Free Predicate Trial Logic (BFPTL), which is parallel to the predicate-free part of a pure CAPC. This treatise, presenting some of my findings, is alternatively called “the Theory of Trial Logic” (“the TTL”) or “the Trial Logic Theory” (“the TLT”). The treatise reopens the entire topic of symbolic logic that is called “decision problem” and that Church actually closed by the fact of synecdochically calling the specific dual decision problem, the insolvability of which he had proved, by the generic name “decision problem”, without the qualifier “dual”. Any additional axiom that is incompatible with the algebraic decision method of the trial logic and that is therefore detrimental for that method is regarded as one belonging to either to another logistic system or to mathematics.

Starting from the primary representation of neutrosophic information, namely the degree of truth, degree of indeterminacy and degree of falsity, we define a nuanced representation in a penta valued fuzzy space, described by the index of truth, index of falsity, index of ignorance, index of contradiction and index of hesitance. Also, it was constructed an associated penta valued logic and then using this logic, it was defined for the proposed penta valued structure the following operators: union, intersection, negation, complement and dual. Then, the penta valued representation is extended to a hexa valued one, adding the sixth component, namely the index of ambiguity.

Prooving it would mean knowing how to build the Universe.
That is the future that people evolution will lead to.
To build the Universee one needs to know the details about the corresponding Hilbert Space since Universe = Hilbert Space,
and Riemann Hypothesis solution is equivalent to the knowing the linear operator in that Hilbert Space that is called "L" which has the eigenvalues equal to the zeros of Riemann Function.

Предлагается принципиально новый метод оптимизации. В отличие от классической постановки задачи:
а) Дан функционал – найти его минималь.
Рассматриваются также задачи:
б) найти более «узкое» подмножество, содержащее абсолютную минималь;
в) найти подмножество решений лучших, чем данное;
г) найти оценки снизу данного функционала.
В настоящее время большинство исследователей, работающих в области оптимизации заняты решение задачи в классической постановке – отысканием точной минимали. Инженера же, как правило, в реальных задачах интересует подмножество квази-оптимальных решений, выбирая из которого, он заранее уверен, что получит значение функционала не хуже заданной величины (задача в) и оценка снизу, показывающая насколько он далек от точного оптимального решения (задача г). Кроме того у него есть много дополнительных соображений, которые нельзя учесть в математической модели или которые бы ее сильно усложнили. Постановка задачи в форме «в» дает ему определенную свободу выбора.
This method, called the “Method of Deformation of Functional (Extreme)”, solves for a total minimum and finds a solution set near the optimum. Solutions found by this method can be exact or approximate. Most other methods solve only for a unique local minimum. The ability to create a set of solutions rather than a unique solution has important practical ramifications in many designs, economic and scientific problems because a unique solution usually is difficult to realize in practice.
This method has the additional virtue of a simple proof, one that is useful for studying other methods of optimization, since most other methods can be delivered from the Method of Deformation.

In computer science, a character set $\Sigma$ is often defined. Then, Kleene plus and Kleene star for formal language are defined. Then, $\Sigma^{+} = \Sigma^{*}\Sigma$ is proved, which means every string (set) in $\Sigma^{+}$ can be represented as a concatenation of a set in $\Sigma^{*}$ and a set in $\Sigma$. However, if one forms a set that cannot be defined by a formula but what people would believe as existing, then while the proof itself does not break down, it may be possible that state of matter is inconsistent. This paper explores this possibility.

This paper uses its own peculiar lettering system for each paragraph.
This paper proposes an overall solution to Godel’s incompleteness theorem and the Gödel sentence. Both are handled as one, by using Gödel numbers as the exemplary objects of incompleteness.
New terms and tools are introduced for quantification that creates a more synthetic (logical, reasonable, coherent) intervention and inter-weaving into these now classical problems of the assumptions in the Gödel material and literature.
Asymptotes are used within vertical and horizontal graphs to justify a future that need not be seen as a future in the sense of grammatical future-tense, but as a potential part such systems themselves that we deal with respect to incompleteness.
The thesis is that we can approach incompleteness by using theoretical reasoning and available tools that are allowed in theoretical reasoning to critique the very theory of incompleteness itself. That is the essential Abstract Thesis. It will be seen that a real attempt is attempted.

The Zermelo-Fraenkel-Axiom-of-Choice (ZFC) axioms for set theory appear to be inconsistent. A step in developing this proof is the observation that ZFC would be deductively incomplete if it were consistent. Both points are proven by means of the singleton. The axioms are still too lax on the notion of a 'well-defined set'.

It seems that statements determining features of some algebraic structures behavior are based on just intuitive assumptions or empiric observations and for sake of convenience (simplest example is the phrase: “let’s consider 0! =1”… perhaps, just because sir I. Newton entrusted, so, why not 2, 5, 7.65 – choose any). So, without logical explanation these are looking a little mysterious or sometimes even magic. This article is a humble attempt to get it straight rather formally. Some troubles may appear on the way – e.g. as it was shown earlier (in the ref. [2], for example), there are at least two binary relations hav-ing properties of idempotent equivalences – algebra’s elements that may aspire to be an identity. Apparently, probable obtaining of some well-known results in the text is not an attempt of their re-discovering, but it is rather “check-points” that confirm theory validity, more by token that it was made by using of the only exceptionally formal way, while usually they are obtained rather intuitively. Usually the notion of tensor product is determined for each kind of algebraic structure – especially for modulus (in group theory it is often called direct product – but this is a matter of semantics, so, it’s rather negligible). Here it is shown that tensor product may be introduced without defining of concrete algebraic structure. Without such introduction defining of algebraic operation is strongly complicated.

In this paper we introduce for the first time a new type of structures, called (T, I, F)-Neutrosophic Structures, presented from a neutrosophic logic perspective, and we show particular cases of such structures in geometry and in algebra.
In any field of knowledge, each structure is composed from two parts: a space, and a set of axioms (or laws) acting (governing) on it. If the space, or at least one of its axioms (laws), has some indeterminacy, that structure is a (T, I, F)-Neutrosophic Structure.
The (T, I, F)-Neutrosophic Structures [based on the components T=truth, I=indeterminacy, F=falsehood] are different from the Neutrosophic Algebraic Structures [based on neutrosophic numbers of the form a+bI, where I=indeterminacy and I^n = I], that we rename as Neutrosophic I-Algebraic Structures (meaning algebraic structures based on indeterminacy “I” only). But we can combine both and obtain the (T, I, F)-Neutrosophic I-Algebraic Structures, i.e. algebraic structures based on neutrosophic numbers of the form a+bI, but also having indeterminacy related to the structure space (elements which only partially belong to the space, or elements we know nothing if they belong to the space or not) or indeterminacy related to at least one axiom (or law) acting on the structure space. Then we extend them to Refined (T, I, F)-Neutrosophic Refined I-Algebraic Structures.

Modules (also known as profunctors or distributors) and morphisms among them subsume categories and functors and provide more general and abstract framework to explore the theory of structures. In this book we generalize and redevelop the basic notions and results of category theory using this framework of modules.

This paper presents two variants of penta-valued representation for neutrosophic entropy. The first is an extension of Kaufmann's formula and the second is an extension of Kosko's formula.
Based on the primary three-valued information represented by the degree of truth, degree of falsity and degree of neutrality there are built some penta-valued representations that better highlights some specific features of neutrosophic entropy. Thus, we highlight five features of neutrosophic uncertainty such as ambiguity, ignorance, contradiction, neutrality and saturation. These five features are supplemented until a seven partition of unity by adding two features of neutrosophic certainty such as truth and falsity.
The paper also presents the particular forms of neutrosophic entropy obtained in the case of bifuzzy representations, intuitionistic fuzzy representations, paraconsistent fuzzy representations and finally the case of fuzzy representations.

Paul of Venice (1369-1429) provides a consistency enhancer that resolves Russell's Paradox in naive set theory without using a theory of types. It allows a set of all sets. It also blocks the (diagonal) general proof of Cantor's Theorem on the power set. It is not unlikely that the Zermelo-Fraenkel (ZFC) axioms for set theory are still too lax on the notion of a "well-defined set". The transfinites of ZFC may be a mirage of still imperfect axiomatics w.r.t. the proper foundations for set theory.

> Context \[Bullet] In the philosophy of mathematics there is the distinction between platonism (realism), formalism, and constructivism. There seems to be no distinguishing experiment however to determine which approach is best according to which criteria. Philosophy finds a sounding board in the didactics of mathematics, as the relevant empirical context, instead of mathematics itself. Mathematicians are trained for abstract thought but in class they meet with real world students. Traditional mathematicians resolve their cognitive dissonance by relying on tradition. That tradition however is not targetted at didactic clarity and empirical relevance with respect to psychology. The mathematical curriculum is a mess. Philosophers can go astray when they don't realize the distinction between mathematics and the didactics of mathematics. > Problem \[Bullet] Aristotle distinguished between potential and actual infinite, Cantor proposed the transfinites, and Occam would want to reject those transfinites if they aren't really necessary. My book "A Logic of Exceptions" already refuted 'the' general proof of Cantor's Theorem on the power set, so that the latter holds only for finite sets but not for 'any' set. There still remains Cantor's diagonal argument on the real numbers. > Results \[Bullet] There is a 'bijection by abstraction' between \[DoubleStruckCapitalN] and \[DoubleStruckCapitalR]. Potential and actual infinity are two faces of the same coin. Potential infinity associates with counting, actual infinity with the continuum, but they would be 'equally large'. The notion of a limit in \[DoubleStruckCapitalR] cannot be defined independently from the construction of \[DoubleStruckCapitalR] itself. Occam's razor eliminates Cantor's transfinites. > Constructivist content \[Bullet] Constructive steps Subscript[S, 1], ..., Subscript[S, 5] are identified, where Subscript[S, 3] gives potential infinity and Subscript[S, 4] actual infinity. The latter is taken as "proper constructivism" and it contains abstraction. The confusions about Subscript[S, 6], nonconstructivism and the transfinites, derive rather from logic than from infinity.

Adding some reasonable properties to the Gödelian system of Peano Arithmetic creates a new system for which Gödel's completeness theorems collapse and the Gödeliar becomes the Liar paradox again. Rejection of those properties is difficult since they are reasonable. Three-valued logic is a better option to deal with the Liar and its variants.

In this paper the author submits a proof using the Power Set relation for the existence of a transfinite cardinal strictly smaller than Aleph Zero, the cardinality of the Naturals. Further, it can be established taking these arguments to their logical conclusion that even smaller transfinite cardinals exist. In addition, as a lemma using these new found and revolutionary concepts, the author conjectures that some outstanding unresolved problems in number theory can be brought to heel. Specifically, a proof of the twin prime conjecture is given.

The paper presents some steps for multi-valued representation of neutrosophic information. These steps are provided in the framework of multi-valued logics using the following logical value: true, false, neutral, unknown and saturated. Also, this approach provides some calculus formulae for the following neutrosophic features: truth, falsity, neutrality, ignorance, under-definedness, over-definedness, saturation and entropy. In addition, it was defined net truth, definedness and neutrosophic score.

In this book the authors for the first time have merged vertices and edges of lattices to get a new structure which may or may not be a lattice but is always a graph. This merging is done for graph too which will be used in the merging of fuzzy models. Further merging of graphs leads to the merging of matrices; both these concepts play a vital role in merging the fuzzy and neutrosophic models.
Several open conjectures are suggested.

Well-ordering of the Reals@@ presents a major challenge in Set theory. Under the standard Zermelo Fraenkel Set theory (ZF) with the Axiom of Choice (ZFC), a well-ordering of the Reals is indeed possible. However the Axiom of Choice (AC) had to be introduced to the original ZF theory which is then shown equivalent to the well-ordering theorem. Despite the result however, no way has still been found of actually constructing a well-ordered Set of Reals. In this paper the author attempts to generate a well ordered Set of Reals without using the AC i.e. under ZF theory itself using the Axiom of the Power Set as the guiding principle.

Standard mathematics involves such notions as infinitely small/large, continuity and standard division. However, some of these notions are treated differently in traditional and constructive versions. This mathematics is usually treated as fundamental while finite mathematics is treated as inferior. Standard mathematics has foundational problems (as follows, for example, from G\"{o}del's incompleteness theorems) but people usually believe that this is less important than the fact that it describes many experimental data with high accuracy. We argue that the situation is the opposite: standard mathematics is only a special case of finite one in the
formal limit when the characteristic of the ring or field used in finite mathematics goes to infinity. Therefore foundational problems
in standard mathematics are not fundamental.

If B(P) is the truth value of proposition P then connectives could be translated to arithmetic operation in the congruent expression of 2 as described below.
B(~p)≡1+B(p)( mod 2 ),B(p∧q)≡B(p)B(q)( mod 2 )
B(p∨q)≡B(p)+B(q)+B(p)B(q)( mod 2 )
B(p⟶q)≡1+B(p)+B(p)B(q)( mod 2 )
B(p⟷q)≡1+B(p)+B(q)(mod 2)
By using this, logical laws could be proved, compound proposition could be simplified, and logical equation could be solved.

For that devise a new system of numbers, in which the real numbers are represented on the y-axis and complex numbers on the x-axis. Inside such a system, we incorporate the equivalent Ideal Fuzzy Logic that can be used by the machine to predict and avoid mishaps.

This paper introduces a new type of set called the Sohraab-Hyder set or the SH set which is quite different from the well known and studied set of the Set Theory. This new set theory is logically consistent and leads to some fascinating results such as, (1) the necessary existence of an ultimate SH set that created itself in pre-eternity and will continue to exist to post-eternity, (2) the ultimate SH set is self sufficient, (2) the ultimate SH set must give rise to infinite number of other SH sets which represent logically consistent algebras and geometries, (3) the ultimate SH set must give rise to the existence of infinite universes, including our own, (4) the ultimate SH set must give rise to mathematical cells, organs and organisms which undergo must undergo evolution, (5) some of these mathematical cells, organs and organisms are same as the organic cells, organs and organisms which leads to the conclusion that the evolution of organisms is a mathematical fact and finally, (6) it is shown that every living and non-living entity in the universe, with the universe included of course, is a matrix of 0's and 1's.

This paper critically examines the Cantor Diagonal Argument (CDA) that is used in
set theory to draw a distinction between the cardinality of the natural numbers and
that of the real numbers. In the absence of a verified English translation of the original
1891 Cantor paper from which it is said to be derived, the CDA is discussed here
using a consensus from the forms found in a range of published sources (from
"popular" to "professional"). Some general comments are made on these sources. The
discussion then focusses on the CDA as applied to the correspondence between the set
of the natural numbers, and the set of real numbers in the open range (0,1) in their
expansion from decimal digits (0.123… etc.).
Four points critical of the CDA are raised: (1) The conventional presentation of the
CDA forms a putative new real number (X) from the "diagonal" of the chosen list of
real numbers and which is therefore not on this initial list; however, it omits to
consider that it may indeed be on the later part of the list, which is never exhausted
however far the "diagonal" list is extended. (2) This aspect, combined with the fact
that X is still composed of decimal digits, that is, it is a real number as defined,
indicates that it must be on the later part of the list, that is, it is not a "new" number at
all. (3) The conventional application of the CDA apparently leads to one putative
"new" real number (X); however, the logical extension of this in its "exhaustive"
application, that is, by using all possible different methods of alteration of the decimal
digits on the "diagonal", and by reordering the list in all possible ways, leads to a list
of putative "new" real numbers that become orders of magnitude longer than the
chosen "diagonal" list. (4) The CDA is apparently considered to be a method that is
applicable generally; however, testing this applicability with the natural numbers
themselves leads to this contradiction.
Following on from this, it is found that it indeed is possible to set up a one-to-one
correspondence between the natural numbers and the real numbers in (0,1), that is, !
⇔ "; this takes the form: … a3 a2 a1 ⇔ 0. a1 a2 a3 …, where the right hand
extension of the natural number is intended to be a mirror image of the left hand
extension of the real number. This may be extended to the general case of real
numbers - that is, not limited to the range (0,1) - by intercalation of the digit sequence
of its decimal fraction part into the sequence of the natural number part, giving the
one-to-one-correspondence: … A3 a3 A2 a2 A1 a1 ⇔ ... A3 A2 A1. a1 a2 a3 …
Additionally, a form of the CDA was presented by Wilfred Hodges in his 1998
critical review of "hopeless papers" dealing with the CDA; this form is also examined
from the same viewpoints, and to the same conclusions.
Finally, some comments are made on the concept of "infinity", pointing out that to
consider this as an entity is a category error, since it simply represents an absence, that
is, the absence of a termination to a process.

This paper critically examines the Cantor Diagonal Argument (CDA) that is used in
set theory to draw a distinction between the cardinality of the natural numbers and
that of the real numbers. In the absence of a verified English translation of the original
1891 Cantor paper from which it is said to be derived, the CDA is discussed here
using a consensus from the forms found in a range of published sources (from
"popular" to "professional"). Some general comments are made on these sources. The
discussion then focusses on the CDA as applied to the correspondence between the set
of the natural numbers, and the set of real numbers in the open range (0,1) in their
expansion from decimal digits (0.123… etc.).
Four points critical of the CDA are raised: (1) The conventional presentation of the
CDA forms a putative new real number (X) from the "diagonal" of the chosen list of
real numbers and which is therefore not on this initial list; however, it omits to
consider that it may indeed be on the later part of the list, which is never exhausted
however far the "diagonal" list is extended. (2) This aspect, combined with the fact
that X is still composed of decimal digits, that is, it is a real number as defined,
indicates that it must be on the later part of the list, that is, it is not a "new" number at
all. (3) The conventional application of the CDA leads to one putative "new" real
number (X); however, the logical extension of this in its "exhaustive" application, that
is, by using all possible different methods of alteration of the decimal digits on the
"diagonal", and by reordering the list in all possible ways, leads to a list of putative
"new" real numbers that become orders of magnitude longer than the chosen
"diagonal" list. (4) The CDA is apparently considered to be a method that is
applicable generally; however, testing this applicability with the natural numbers
themselves leads to a contradiction.
Following on from this, it is found that it indeed is possible to set up a one-to-one
correspondence between the natural numbers and the real numbers in (0,1), that is, N
⇔ R; this takes the form: … a3 a2 a1 ⇔ 0. a1 a2 a3 …, where the right hand extension
of the natural number is intended to be a mirror image of the left hand extension of
the real number. It is also shown how this may be extended to real numbers outside
the range (0,1).

The division of zero by zero turns out to be a long lasting and not ending puzzle in mathematics and physics. An end of this long discussion is not in sight. In particular zero divided by zero is treated as indeterminate thus that a result cannot be found out. It is the purpose of this publication to solve the problem of the division of zero by zero while relying on the general validity of classical logic. According to classical logic, zero divided by zero is one.

This paper addresses the concept of selectivity using a main set and an auxiliary set, the auxiliary serves the purpose of deciding which elements do or do not fit together within the output sets chosen based on the elements of the main set.
This paper also presents an approach of comparing sets based on a defined relation, the sets’ properties, and the elementary properties being total compatibility and total incompatibility.
The problem classes P and NP are two sets considered under the criteria of distinguishability, then the possibility of comparison of the two sets is discussed. The proposed comparison presents a distinction between P and NP.

Many have suggested that the infinite set has a fundamental problem. The usual complaint rails against the actually infinite which (say critics of various finitist persuasions) unjustifiably goes beyond the finite. Here we identify the exact opposite. The problem of the infinite set defined to have an identity (content) that is specified and restricted to be forever finite .
Set theory is taken at its word. The existence of the infinite set and the representation of irrational reals as infinite sets of terms is accepted. In this context, it is shown that the standard definition of the infinite countable set is inconsistent with the existence of its own classic convergents of construction. If the set is infinite then it must be quite unlike that which set theory asserts it to be.
Set theory found itself in some trouble over a century ago trusting an unrestricted anthropic comprehension. But serious doubt is cast on the validity of infinite sets which have been defined by a comprehension which overly-restricts their content.

Curry's paradox is generally considered to be one of the hardest paradoxes to solve. It is shown here that the paradox can be arrived in fewer steps and also for a different term of the original biconditional. Further, using different approaches, it is also shown that the conclusion of the paradox must always be false and this is not paradoxical but it is expected to be so. One of the approaches points out that the starting biconditional of the paradox amounts to a false definition or assertion which consequently leads to a false conclusion. Therefore, the solution is trivial and the paradox turns out to be no paradox at all. Despite that fact that verifying the truth value of the first biconditional of the paradox is trivial, mathematicians and logicians have failed to do so and merely assumed that it is true. Taking this into consideration that it is false, the paradox is however dismissed. This conclusion puts to rest an important paradox that preoccupies logicians and points out the importance of verifying one's assumptions.

By proving that his “last theorem” (FLT) is true for the integral exponent n = 3, Fermat took the first step in a standard method of proving there exists no greatest lower bound on n for which FLT is true, thus proving the theorem. Unfortunately, there are two reasons why the standard method of proof is not available for FLT. First, transitive inequality lies at the heart of that method. Secondly, FLT admits to a change from > to < rendering their transitive natures unavailable. A related, self evident symmetry illustrates another problem that would have plagued Fermat and centuries of successors. FLT asserts such a narrow proposition, it is difficult to find an antecedent while easy to find a non equivalent consequence. For example, if FLT asserted that the exponent n is even, then FLT would be equivalent to the proposition that Fermat’s equation has two solutions, one for positive bases and one for their negative counterparts. This could be addressed with conservative transformations. The example provided by FLT motivates the use of an early paper by the author to prove a theorem on theorems. The theorem on theorems demonstrates there are infinitely many theorems as difficult to prove as FLT.

Also, it was constructed an associated penta valued logic and then using this logic, it was defined for the proposed penta valued structure the following operators: union, intersection, negation, complement and dual. Then, the penta valued representation is extended to a hexa valued one, adding the sixth component, namely the index of ambiguity.

It seems that statements determining features of some algebraic structures behavior are based on just intuitive assumptions or empiric observations and for sake of convenience (simplest example is the phrase: “let’s consider 0! =1”… perhaps, just because Sir Isaac Newton entrusted, so, why not choose any: e.g. 2, 5, or 7.65). So, without logical explanation these are looking a little mysterious or sometimes even magic. This article is a humble attempt to get it straight rather formally. Some troubles may appear on the way – e.g. as it was shown earlier (in the ref. [2], for example), there are at least two binary relations having properties of idempotent equivalences – algebra’s elements that may aspire to be an identity. Apparently, probable obtaining of some well-known results in the text is not an attempt of their re-discovering, but it is rather “check-points” that confirm theory validity, more by token that it was made by using of the only exceptionally formal way, while usually they are obtained rather intuitively. Usually the notion of tensor product is determined for each kind of algebraic structure – especially for modulus (in group theory it is often called direct product – but this is a matter of semantics, so, it’s rather negligible). Here it is shown that tensor product may be introduced without defining of concrete algebraic structure. Without such introduction defining of algebraic operation is strongly complicated.

Modules (also known as profunctors or distributors) and morphisms among them subsume categories and functors and provide more general and abstract framework to explore the theory of structures, in particular, the notion of universal property. In this book we generalize and redevelop the basic notions and results of various universal constructions in category theory using this framework of modules.

Paul of Venice (1369-1429) provides a consistency condition that resolves Russell's Paradox in naive set theory without using a theory of types. It allows a set of all sets. It also blocks the (diagonal) general proof of Cantor's Theorem (in Russell's form, for the power set). The Zermelo-Fraenkel-Axiom-of-Choice (ZFC) axioms for set theory appear to be inconsistent. They are still too lax on the notion of a well-defined set. The transfinites of ZFC may be a mirage, and a consequence of still imperfect axiomatics in ZFC for the foundations of set theory. For amendment of ZFC two alternatives are mentioned: ZFC-PV (amendment of de Axiom of Separation) or BST (Basic Set Theory).

> Context • In the philosophy of mathematics there is the distinction between platonism (realism), formalism, and constructivism. There seems to be no distinguishing or decisive experiment to determine which approach is best according to non-trivial and self-evident criteria. As an alternative approach it is suggested here that philosophy finds a sounding board in the didactics of mathematics rather than mathematics itself. Philosophers can go astray when they don’t realise the distinction between mathematics (possibly pure modeling) and the didactics of mathematics (an empirical science). The approach also requires that the didactics of mathematics is cleansed of its current errors. Mathematicians are trained for abstract thought but in class they meet with real world students. Traditional mathematicians resolve their cognitive dissonance by relying on tradition. That tradition however is not targetted at didactic clarity and empirical relevance with respect to psychology. The mathematical curriculum is a mess. Mathematical education requires a (constructivist) re-engineering. Better mathematical concepts will also be crucial in other areas, such as e.g. brain research. > Problem • Aristotle distinguished between potential and actual infinite, Cantor proposed the transfinites, and Occam would want to reject those transfinites if they aren’t really necessary. My book “A Logic of Exceptions” already refuted ‘the’ general proof of Cantor's Conjecture on the power set, so that the latter holds only for finite sets but not for ‘any’ set. There still remains Cantor’s diagonal argument on the real numbers. > Results • There is a bijection by abstraction between N and R. Potential and actual infinity are two faces of the same coin. Potential infinity associates with counting, actual infinity with the continuum, but they would be ‘equally large’. The notion of a limit in R cannot be defined independently from the construction of R itself. Occam’s razor eliminates Cantor’s transfinites. > Constructivist content • Constructive steps S1, ..., S5 are identified while S6 gives non-constructivism (possibly the transfinites). Here S3 gives potential infinity and S4 actual infinity. The latter is taken as ‘proper constructivism with abstraction'. The confusions about S6 derive rather from logic than from infinity.

In this paper the author submits a proof using the Power Set relation for the existence of a transfinite cardinal strictly smaller than Aleph Zero, the cardinality of the Naturals. Further, it can be established taking these arguments to their logical conclusion that even smaller transfinite cardinals exist. In addition, as a lemma using these new found and revolutionary concepts, the author conjectures that some outstanding unresolved problems in number theory can be brought to heel. Specifically, a proof of the twin prime conjecture is given.

In 1942 Haskell B. Curry presented what is now called Curry's paradox which can be found in a logic independently of its stand on negation. In recent years there has been a revitalised interest in non-classical solutions to the semantic paradoxes. In this article the non-classical resolution of Curry’s Paradox and Shaw-Kwei's paradox without rejection any contraction postulate is proposed.

It was shown here that just transitive relation may be considered as closure and its presence is necessary and sufficient to order a set linearly, and it is not possible to do this by using other relation’s property – neither reflexivity nor symmetry. By interaction, it occurs due to ambiguity of their definition – it was shown earlier (ref. [3]) they have various appearances. Among them just the only transitivity is determined uniquely. At the same time the last one doesn’t exist separately from any others. Circumstances of their joint existence are clarifying in this article.

Usually itemizing relations’ properties those of them are always pointed out – some appearance of reflexivity, symmetry and transitivity. Also it is not so clear whether they are introduced artificially – i.e. axiomatically, rather for the sake of convenience or it may be done due to inartificial reasons. At the same time an origin of them is not so clear – whether they appear chaotically and independently on each other or there should be rigorous association between them. It is shown here that request of relation’s reversibility leads to these properties’ presence or absence. Often symmetry appearances are defined by using of ambiguous way. In fact, anti-symmetry is not direct negation for symmetry – there is also something that may be called as asymmetry or it may be something else. To avoid it here there was found the unified method of their definition. The same thing may be told about reflexivity and it was shown that just the only intransitivity may be represented as direct negation of transitivity.

Standard mathematics involves such notions as infinitely small/large, continuity and standard division. This mathematics is usually treated as fundamental while finite mathematics is treated as inferior. Standard mathematics has foundational problems (as follows, for example, from G\"{o}del's incompleteness theorems) but it is usually believed that this is less important than the fact that it describes many experimental data with high accuracy. We argue that the situation is the opposite: standard mathematics is only a degenerate case of finite one in the formal limit when the characteristic of the ring or field used in finite mathematics goes to infinity. Therefore foundational problems in standard mathematics are not fundamental.
