In this paper I make the following three conjectures: (I) there exist positive integers k such that the number (30*k)\\(30*k + p) is prime for an infinity of primes p. I used the operator “\\” with the meaning “concatenated to”; (II) there exist primes p such that the number (30*k)\\(30*k + p) is prime for an infinity of values of k; (III) there exist an infinity of primes of the form (30*k)\\(30*k + 1), where k positive integer.

In this paper I define a Smarandache reconcatenated sequence Sr(n) as “the sequence obtained from the terms of a Smarandache concatenated sequence S(n), terms for which was applied the operation of consecutive concatenation” and I present six such sequences. Example: for Smarandache consecutive numbers sequence (1, 12, 123, 1234, 12345...), the Smarandache reconcatenated consecutive numbers sequence has the terms: 1, 112, 112123, 1121231234, 112123123412345...). According to the same pattern, we can define back reconcatenated sequences (the terms of the Smarandache back reconcatenated consecutive numbers sequence, noted Sbr(n), are 1, 121, 123121, 1234123121...).

We look here at the geometry of zeta(3). By piling cubes a 3D shape is defined which has a volume of zeta(3). This shape is a double integral form for zeta(3). Considering the centroid of this shape leads to an experimental estimate for zeta(3). Cutting the shape parallel to the x axis reproduces the dilogarithmic relationship to zeta(3). Cutting the shape in the z axis reproduces the logarithmic version of Riemann’s formula for zeta(3). Geometrical considerations also reproduce formula for the polylog of a half Lin(1/2) for n=2 and 3.
These are illustrations of number geometry.

Of course, the conjectures (III) and (IV) imply that there exist an infinity of pairs of twin primes.

In this paper I make the following conjecture on an infinity of subsequences of primes in Smarandache prime-partial-digital sequence, defined as the sequence of prime numbers which admit a deconcatenation into a set of primes: for any prime p which admits a deconcatenation in k primes larger than 3 is true that there exist a number of k sequences of primes P1, P2,...,Pk, each one having an infinity of prime terms which also admit a deconcatenation in prime numbers, obtained replacing a prime q in p with primes having the same digital root as q (example: for the prime 547 there exist an infinite sequence of primes obtained replacing 5 with primes having the digital root equal to 5 (2347, 13147, 14947, ...) and also an infinite sequence of primes obtained replacing 47 with primes having the digital root equal to 2 (5101, 5227, 5281,...).

I conjecture that there exist such prime p for every composite number.

In this paper, we show that for all even integers “2n”, there exists infinite
positive integers “d” greater than one, such that their product “2nd” is a sum of two
primes. Any two odd primes add to give even integers. However this general method
does not allow us to understand the property or relationship among even numbers
numbers derived in this manner. On the other hand, our results suggests existence
of even integers of the specific form “2nd” that can be written as a sum of two
primes.

The Kurepa conjecture states that the gcd (!n,n!) is equal to 2 for all n=2,3,….Although this conjecture has not been proven, in this paper we study the implication of a true Kurepa conjecture. We use (!n)/2 and (n!)/2 as components of two distinct arithmetic progressions and propose that both should have infinitely many primes as known from Dirichlet’s theorem of Arithmetic progressions and these are named as Dirichlet-Kurepa primes Type 1 and Type 2 in their honor.

In this paper I make the following conjecture: for any p prime, p > 5, there exist an infinity of k positive integers such that the number q obtained concatenating to the right p with p + 30*k is prime (examples: for p = 13, the least k for which q is prime is 2 because 1373 is prime; for p = 104729, the least k for which q is prime is 3 because 104729104819 is prime). It is notable the small values of k for which primes q are obtained, even in the case of primes p having 20 digits, so this formula could be a way to easily find, starting from a prime p, a prime q having twice as many digits!

Though the well known Fermat’s conjecture on the diophantine equation x^n + y^n = z^n is named “Fermat’s big theorem”, in fact probably much more important for number theory is what is called “Fermat’s little theorem” which was the most important step up to that time in order to discover a primality criterion. This exceptional criterion of primality still has its exceptions: Fermat pseudoprimes, numbers which “behave” like primes though they are no primes; but they are still a class of numbers at least as interesting as the class of primes. Among Fermat pseudoprimes two classes of numbers are particularly distinguished: Poulet numbers (relative Fermat pseudoprimes) and Carmichael numbers (absolute Fermat pseudoprimes). The initial aim of this paper was only to see which Poulet numbers can be obtained concatenating primes (or, in other words, whichever admit a deconcatenation in prime numbers) but, inspired by a characteristic of a subset of Poulet numbers, I also made the following conjecture: there exist an infinity of primes p obtained concatenating to the right a prime q having the sum of the digits s(q) equal to a multiple of 5 with 3.

This book brings together fifty-two papers regarding primes and Fermat pseudoprimes, submitted by the author to the scientific database Research Gate. Part One of this book, “Sequences of primes and conjectures on them”, contains papers on sequences of primes, squares of primes, semiprimes, pairs, triplets and quadruplets of primes and conjectures on them. This part also contains papers on possible methods to obtain large primes, some of them based on concatenation, some of them on other arithmetical operations. It is also introduced a new notion, “Smarandache-Coman sequences of primes”, defined as “all sequences of primes obtained from the Smarandache sequences using any arithmetical operation”. Part Two of this book, “Sequences of Fermat pseudoprimes and conjecture on them”, contains sequences of Poulet and Carmichael numbers. Among these papers there is a list of thirty-six polynomials and formulas that generate sequences of Fermat pseudoprimes. Part Three of this book, “Prime producing quadratic polynomials”, contains three papers which list few already known such polynomials, that generate more than 20, 30 or even 40 primes in a row, and few such polynomials discoverd by the author himself (in a review of records in the field of prime generating polynomials, written by Dress and Landreau, two mathematicians well known for their contributions in this field, the author is mentioned with 18 prime producing quadratic polynomials).

In this paper I make the following four conjectures on the Smarandache prime-partial-digital sequence defined as the sequence of prime numbers which admit a deconcatenation into a set of primes: (I) there exist an infinity of primes p obtained concatenating two primes m and n, both of the form 6*k + 1, such that n = m*h – h + 1 , where h positive integer; (II) there exist an infinity of primes p obtained concatenating two primes m and n, both of the form 6*k - 1, such that n = m*h + h - 1 , where h positive integer; (III) there exist an infinity of primes p obtained concatenating two primes m and n, both of the form 6*k + 1, such that n + m - 1 is prime or power of prime; (IV) there exist an infinity of primes p obtained concatenating two primes m and n, both of the form 6*k - 1, such that n - m + 1 is prime or power of prime. Note that almost all from the first 65 primes obtained concatenating two primes of the form 6k + 1 (exceptions: 3779, 4373, 6173, 6719, 6779), and all the first 65 primes obtained concatenating two primes of the form 6k - 1, belong to one of the four sequences considered by the conjectures above.

Using a clear and straightforward approach, we prove new ternary (base 3) digit extraction BBP-type formulas for polylogarithm constants. Some known results are also rediscovered in a more direct and elegant manner. A previously unproved degree~4 ternary formula is also proved. Finally, a couple of ternary zero relations are established, which prove two known but hitherto unproved formulas.

In this paper I discuss an algorithm which will solve a very famous puzzle involving a monkey, few men and some coconuts. The puzzle involves a group of n men who have an unknown number of coconuts among them. At night, while the others are asleep, one of the men divides the coconuts in n parts and hides his share. While dividing, he discovers that there is one extra coconut, which he gives away to a monkey. Exactly the same thing happens with the rest of the men, one by one. They all hide their share, are left with one extra coconut that cannot be divided, which they give to the monkey. The next morning they again divide the coconuts together equally among themselves, with no extra coconut remaining this time. The puzzle is to find out the initial number of coconuts.

To make an introduction to a book about arithmetic it is always difficult, because even most apparently simple assertions in this area of study may hide unsuspected inaccuracies, so one must always approach arithmetic with attention and care; and seriousness, because, in spite of the many games based on numbers, arithmetic is not a game. For this reason, I will avoid to do a naive and enthusiastic apology of arithmetic and also to get into a scholarly dissertation on the nature or the purpose of arithmetic. Instead of this, I will summarize this book, which brings together several articles regarding primes and Fermat pseudoprimes, submitted by the author to the preprint scientific database Research Gate. Part One of this book, “Sequences of primes and conjectures on them”, brings together thirty-two papers regarding sequences of primes, sequences of squares of primes, sequences of certain types of semiprimes, also few types of pairs, triplets and quadruplets of primes and conjectures on all of these sequences. There are also few papers regarding possible methods to obtain large primes or very large numbers with very few prime factors, some of them based on concatenation, some of them on other arithmetic operations. It is also introduced a new notion: “Smarandache-Coman sequences of primes”, defined as “all sequences of primes obtained from the terms of Smarandache sequences using any arithmetical operation” (for instance, the sequence of primes obtained concatenating to the right with the digit one the terms of Smarandache consecutive numbers sequence). Part Two of this book, “Sequences of Fermat pseudoprimes and conjectures on them”, brings together seventeen papers on sequences of Poulet numbers and Carmichael numbers, i.e. the Fermat pseudoprimes to base 2 and the absolute Fermat pseudoprimes, two classes of numbers that fascinated the author for long time. Among these papers there is a list of thirty-six polynomials and formulas that generate sequences of Fermat pseudoprimes. Part Three of this book, “Prime producing quadratic polynomials”, contains three papers which list some already known such polynomials, that generate more than 20, 30 or even 40 primes in a row, and few such polynomials discovered by the author himself (in a review of records in the field of prime generating polynomials, written by Dress and Landreau, two French mathematicians well known for records in this field, review that can be found on the web address

Note that for 25 from the first 30 odd numbers n not divisible by 3 the number m obtained belongs to one of the two sequences considered by the conjectures above.

In 1997, Andrew Beal announced the following conjecture : \textit{Let $A, B,C, m,n$, and $l$ be positive integers with $m,n,l > 2$. If $A^m + B^n = C^l$ then $A, B,$ and $C$ have a common factor.} We begin to construct the polynomial $P(x)=(x-A^m)(x-B^n)(x+C^l)=x^3-px+q$ with $p,q$ integers depending of $A^m,B^n$ and $C^l$. We resolve $x^3-px+q=0$ and we obtain the three roots $x_1,x_2,x_3$ as functions of $p,q$ and a parameter $\theta$. Since $A^m,B^n,-C^l$ are the only roots of $x^3-px+q=0$, we discuss the conditions that $x_1,x_2,x_3$ are integers. Three numerical examples are also given.

In a previous paper, “Fourteen Smarandache-Coman sequences of primes”, I defined the “Smarandache-Coman sequences” as “all the sequences of primes obtained from the Smarandache concatenated sequences using basic arithmetical operations between the terms of such a sequence, like for instance the sum or the difference between two consecutive terms plus or minus a fixed positive integer, the partial sums, any other possible basic operations between terms like a(n) + a(n+2) – a(n+1), or on a term like a(n) + S(a(n)), where S(a(n)) is the sum of the digits of the term a(n) etc.” In this paper I extend the notion to the sequences of primes obtained from the Smarandache concatenated sequences using any arithmetical operation and I present seven sequences obtained from the Smarandache concatenated sequences using concatenation between the terms of the sequence and other numbers and also fourteen conjectures on them.

Modern scientist come close to Einstein, the most prominent physicist of the twentieth century and may be of all time. Still, the question is justified, can there be ever another Einstein? Less well known, though of fundamental importance, are Einstein's contributions to the philosophy of science. Einstein's is well known for his conviction that scientist should trust simplicity. Einstein proclaimed that we can discover the true laws of nature or proof theorems by seeking those with the most simple mathematical formulation. Einstein's faith in the supreme power of mathematical simplicity was strong. Such an approach to scientific investigation is of strategic use, since by time the hypotheses from which scientists starts become ever more abstract and more remote from experience. Especially, under conditions where scientific investigations are moving steadily into domains ever further removed from direct contact with an experiment or observation, the starting point should be as simple as possible. This point of view, whose exact formulation while investi-gating the problem of the division of zero by zero may meet with great difficulties, may justify our trust that the problem of the division of zero by zero is solved.

In this paper I make the following conjecture on the numbers of the form n = 6*p*q + 1, where p and q are primes and q = k*p – k + 1: There exist an infinity of n primes for any k positive integer, k > 1. Note that the conjecture implies that there exist an infinity of pairs of primes [p, q] such that q = k*p – k + 1, for any k positive integer, k > 1, which I already conjectured in previous papers, as well as that there exist an infinity of pairs of primes [p, q] such that q = k*p + k - 1, for any k positive integer, k > 1.

In this paper I make the following observation: let n1, n2,..., ni be the ordered set of the odd semiprimes not divisible by 3; then the period of the rational number which is the sum 1/(n1 – 1) + 1/(n2 – 1) +...+ 1/(ni - 1) seems to be always (for any i) divisible by 48. This is not the fact when the semiprimes n1, n2,..., ni are not the ordered set of such semiprimes but few randomly taken (even consecutive) such semiprimes.

In this paper I make the following observation: let p1, p2,..., pi be the ordered set of the 2-Poulet numbers; then the length of the period of the rational number which is the sum 1/(p1 – 1) + 1/(p2 – 1) +...+ 1/(ni - 1) seems to be always (for any i > 2) divisible by 240. This is not the fact when the numbers p1, p2,..., pi are not the ordered set of 2-Poulet numbers but few randomly taken (even consecutive) 2-Poulet numbers. For a related topic see my previous paper “A pattern that relates Carmichael numbers to the number 66” where I noticed that the length of the period of the rational number which is the sum 1/(c1 – 1) + 1/(c2 – 1) +...+ 1/( ci - 1), where c1, c2, ..., ci is the ordered set of Carmichael numbers, seems to be always divisible by 66.

In this paper i have presented a partial solution of open problem so called Goldbach’s
conjecture in number theory, which consists in the fact that: “Every even number can be
expressed as a sum of two prime numbers”. In this paper I have set up a hypothesis, which helps
in my line of proof of Goldbach hypothesis. I very much hope that this hypothesis be easier to
prove.
