Les Empilements D'hexagone et Quelques Méthodes

Authors: Simon Plouffe
Comments: 26 Pages. This is a talk made in Montréal in 1992.

En physique on modélise le comportement des gaz, du cristal de glace et du ferromagnétisme par l'étude de l'empilement d'objets sur le plan Z*Z, ou dans l'espace. On tente d'expliquer surtout les phénomènes de transition de phase. Ce qui intéresse les physiciens c'est le comportement du système lorsque la température T tend vers Tc, une température à laquelle se fait la transition entre deux états. Si on a une formule explicite on peut simuler pour de grandes valeurs. On compte, en prenant modèle sur les partitions ordinaires. L'énergie d'interaction des molécules entre elles étant comptée comme une "arête" entre 2 sommets i et j du plan Z*Z. L'interaction se mesure alors avec 2 variables qu'on somme sur toutes les positions possibles. On cherche donc la limite quand N tend vers l'infini. (N grand : beaucoup de molécules).

Computing the Generating Function of a Series Given Its First Few Terms

Authors: Simon Plouffe, François Bergeron
Comments: 6 Pages. Published in 1991

We outline an approach for the computation of a good candidate for the generating function of a power series for which only the first few coefficients are known. More precisely, if the derivative, the logarithmic derivative, the reversion, or another transformation of a given power series (even with polynomial coefficients) appears to admit a rational generating function, we compute the generating function of the original series by applying the inverse of those transformations to the rational generating function found.

Recognizing Numerical Constants

Authors: Simon Plouffe, David H. Bailey
Comments: 17 Pages. Published in 1996

The advent of inexpensive, high-performance computers and new efficient algorithms have made possible the automatic recognition of numerically computed constants. In other words, techniques now exist for determining, within certain limits, whether a computed real or complex number can be written as a simple expression involving the classical constants of mathematics. These techniques will be illustrated by discussing the recognition of Euler sum constants, and also the discovery of new formulas for π and other constants, formulas that permit individual digits to be extracted from their expansions.

Comments: 18 Pages. This is third manuscript for the article.

If every positive integer is able to be operated to 1 by the set operational rule of the Collatz conjecture, then begin with 1, we can get all positive integers by operations on the contrary of the set operational rule for infinite many times. In this article, we will apply the mathematical induction with the help of certain operations by each other’s- opposed operational rules to prove that the Collatz conjecture is tenable.

The Computation of Certain Numbers Using a Ruler and Compass

Authors: Simon Plouffe
Comments: 4 Pages.

We present a method for computing some numbers bit by bit using only a ruler and compass, and illustrate it by applying it to arctan(X)/π. The method is a spigot algorithm and can be applied to numbers that are constructible over the unit circle and the ellipse. The method is precise enough to produce about 20 bits of a number, that is, 6 decimal digits in a matter of minutes. This is surprising, since we do no actual calculations.

When π(n) Divides N and When it Does not

Authors: Germán Paz
Comments: 6 Pages. Main text in English; abstract in English and Spanish. /// Texto principal en inglés; resumen en inglés y en español.

Let $\pi(n)$ denote the prime-counting function. In this paper we work with explicit formulas for $\pi(n)$ that are valid for infinitely many positive integers $n$, and we prove that if $n\ge 60184$ and $\operatorname{frac}(\ln n)=\ln n-\lfloor\ln n\rfloor>0.5$, then $\pi(n)$ does not divide $n$. Based on this result, we show that if $e$ is the base of the natural logarithm, $a$ is a fixed integer $\ge 11$ and $n$ is any integer in the interval $[e^{a+0.5},e^{a+1}]$, then $\pi(n)\nmid n$. In addition, we prove that if $n\ge 60184$ and $n/\pi(n)$ is an integer, then $n$ is a multiple of $\lfloor\ln n-1\rfloor$ located in the interval $[e^{\lfloor\ln n-1\rfloor+1},e^{\lfloor\ln n-1\rfloor+1.5}]$.

Además, demostramos que si $n\ge 60184$ y $n/\pi(n)$ es entero, entonces $n$ es un múltiplo de $\lfloor\ln n-1\rfloor$ ubicado en el intervalo $[e^{\lfloor\ln n-1\rfloor+1},e^{\lfloor\ln n-1\rfloor+1.5}]$.

One Hundred and Fifty Conjectures on Primes, Many Based on the Observation of Fermat Pseudoprimes

Authors: Marius Coman
Comments: 87 Pages.

In two of my previous published books, “Two hundred conjectures and one hundred and fifty open problems on primes”, respectively “Conjectures on primes and Fermat pseudoprimes, many based on Smarandache function”, I already expressed my conviction that the study of Fermat pseudoprimes, fascinating numbers that seem to be a little bit more willing to let themselves ordered and understood than the prime numbers, can help a lot in understanding these latter. This book brings together thirty-eight papers on prime numbers, many of them supporting the author’s belief, expressed above, namely that new ordered patterns can be discovered in the “undisciplined” set of prime numbers, observing the ordered patterns in the set of Fermat pseudoprimes, especially in the set of Carmichael numbers, the absolute Fermat pseudoprimes, and in the set of Poulet (sometimes also called Sarrus) numbers, the relative Fermat pseudoprimes to base two. Few papers, which are not based on the observation of pseudoprimes, though apparently heterogenous, still have something in common: they are all directed toward the same goal, discovery of new patterns in the set of primes, using the same means, namely the old and reliable integers. Part One of this book of collected papers contains one hundred and fifty conjectures on primes and Part Two of this book brings together the articles regarding primes, submitted by the author to the preprint scientific database Vixra, representing the context of the conjectures listed in Part One.

The Proof for Non-existence of Perfect Cuboid

Authors: Bambore Dawit
Comments: 9 Pages. the proof is short cut, there are instructions and results

This paper shows the non-existence of perfect cuboid by using two tools, the first is representing Pythagoras triplets by two numbers and the second is realizing the impossibility of two similar equations for the same problem at the same time in different ways and the variables of one is relatively less than the other. When we express all Pythagoras triplets in perfect cuboid problem and rearrange it we can get a single equation that can express perfect cuboid. Unfortunately perfect cuboid has more than two similar equations that can express it and contradict one another.

A New Bold Conjecture About a Way in Which Any Prime Can be Written

Authors: Marius Coman
Comments: 2 Pages.

In this paper I make a conjecture which states that any prime greater than or equal to 53 can be written at least in one way as a sum of three odd primes, not necessarily distinct, of the same form from the following four ones: 10k + 1, 10k + 3, 10k + 7 or 10k + 9.

Proof that an Infinite Number of Mersenne Prime Numbers Exit

Authors: Stephen Marshall
Comments: 11 Pages.

This paper presents a complete and exhaustive proof of the infinitude of Mersenne prime numbers. The approach to this proof uses same logic that Euclid used to prove there are an infinite number of prime numbers. Then we prove that if p > 1 and d > 0 are integers, that p and p + d are both primes if and only if for integer n (see reference 1 and 2): n=(p-1)!(1/p+(-1)dd!/(p + d))+1/p+ 1/(p+d) We use this proof for d = 2p(k+m) - 2p(k) to prove the infinitude of Mersenne prime numbers.

An Amazing Formula for Producing Big Primes Based on the Numbers 25 and 906304

Authors: Marius Coman
Comments: 3 Pages.

In this paper I present a formula for generating big primes and products of very few primes, based on the numbers 25 and 906304, formula equally extremely interesting and extremely simple, id est 25^n + 906304. This formula produces for n from 1 to 30 (and for n = 30 is obtained a number p with not less than 42 digits) only primes or products of maximum four prime factors.

Proof That an Infinite Number of Sophie Germain Primes Exist

Authors: Stephen Marshall
Comments: 6 Pages.

In number theory, a prime number p is a Sophie Germain prime if 2p + 1 is also prime. For example, 29 is a Sophie Germain prime because it is a prime and 2 × 29 + 1 = 59, and 59 is also a prime number. These numbers are named after French mathematician Marie-Sophie Germain. We shall prove that there are an infinite number of Sophie Germain primes.

Proof of Infinite Number of Triplet Primes

Authors: Stephen Marshall
Comments: 12 Pages.

This paper presents a complete and exhaustive proof that an Infinite Number of Triplet Primes exist. The approach to this proof uses same logic that Euclid used to prove there are an infinite number of prime numbers. Then we prove that if p > 1 and d > 0 are integers, that p and p + d are both primes if and only if for integer n (see reference 1 and 2): n =(p−1)!(1/p+(−1)d(d!)/(p + d)+ 1/(p+1)+ 1/(p+d) We use this proof and Euclid logic to prove only an infinite number of Triplet Primes exist. However we shall begin by assuming that a finite number of Triplet Primes exist, we shall prove a contradiction to the assumption of a finite number, which will prove that an infinite number of Triplet Primes exist.

The Sequence of the Primes

Authors: Anibal Fernando Barral
Comments: 24 Pages.

In mathematics, a prime number is a natural number that is divisible only by 1 and itself. For centuries, the search for an algorithm that could generate the sequence of these numbers became a mystery. Perhaps the problem arises at the beginning of the enterprise, that is, the search for a single algorithm. I noticed that all the primes without exception increased by one unit in some cases, or decreased by one unit in the other cases result in a multiple of 6 (six) Example: 5+1=6 ; 7-1=6 ; 11+1=12 ; 13-1=12 ; 17+1=18 ; 19-1=18 ; 23+1=24 ; 29+1=30 ; 31-1=30 ; 37-1=36 ; 41+1=42 ; 43-1=42 ; 47+1=48 ; and so on. Then I thought of making it easier to split the problem solving both cases. So are passed to assume the presence of # 2 complementary families of primes. To the number 1000, I worked by hand, a job with some effort but great satisfaction. At this point my algorithms were reliable, but I needed another test. To get to number 60,000 I leaned in a computational program, which compiled a dear friend. I would have liked to get up to 1,000,000 but the limit of 60,000 has been imposed by the processing time of the data. At this point I had no more doubts about the reliability of my algorithms that are developed in continuation.

Comments on Recent Papers by S. Marshall Claiming Proofs of Several Conjectures in Number Theory

Authors: Matthias Lesch
Comments: 3 Pages.

In recent three preprints S. Marshall claims to give proofs of several famous conjectures in number theory, among them the twin prime conjecture and Goldbach's conjecture. A claimed proof of Beal's conjecture would even imply an elementary proof of Fermat's Last Theorem. It is the purpose of this note to point out serious errors. It is the opinion of this author that it is safe to say that the claims of the above mentioned papers are lacking any basis.

La formule d’itération de Mandelbrot Z_(n+1)=Z_n^2+c converge vers un nombre algébrique de degré 4 si c est un rationnel simple.

On the Values of the Function Zeta and Gamma

Authors: Simon Plouffe
Comments: 13 Pages. The abstract in english and the main text in french

An analysis of the function 1/π Arg ζ((1/2)+in) is presented. This analysis permits to find a general expression for that function using elementary functions of floor and fractional part. These formulas bring light to a remark from Freeman Dyson which relates the values of the ζfunction to quasi-crystals. We find these same values for another function which is very similar, namely 1/π Arg Γ((1/4)+in/2). These 2 sets of formula have a definite pattern, the n’th term is related to values like π,ln⁡(π),ln⁡(2),…,log⁡(p), where p is a prime number. The coefficients are closed related to a certain sequence of numbers which counts the number of 0’s from the right in the binary representation of n. These approximations are regular enough to deduce an asymptotic and precise formula. All results presented here are empirical.

Goldbach's Conjecture. Demonstration by Analysis of Arithmetic Progressions.

Authors: Ramón Ruiz
Comments: 34 Pages. This research is based on an approach developed solely to demonstrate the binary Goldbach Conjecture and the Twin Primes Conjecture.

Goldbach's Conjecture statement: “Every even integer greater than 2 can be expressed as the sum of two primes”. Initially, to prove this conjecture, we can form two arithmetic sequences (A and B) different for each even number, with all the natural numbers that can be primes, that can added, in pairs, result in the corresponding even number. By analyzing the pairing process, in general, between all non-prime numbers of sequence A, with terms of sequence B, or vice versa, to obtain the even number, we note that some pairs of primes are always formed. This allow us to develop a non-probabilistic formula, to calculate the approximate number of pairs of primes that meet the conjecture for an even number x. The result of this formula is always equal or greater than 1, and it tends to infinite when x tends to infinite, which allow us to confirm that Goldbach's Conjecture is true. The prime numbers theorem by Carl Friedrich Gauss, the prime numbers theorem in arithmetic progressions and some axioms have been used to complete this investigation.

Twin Primes Conjecture. Demonstration by Analysis of Arithmetic Progressions.

Authors: Ramón Ruiz
Comments: 24 Pages. This research is based on an approach developed solely to demonstrate the Twin Primes Conjecture and the binary Goldbach Conjecture.

Twin Primes Conjecture statement: “There are infinitely many primes p such that (p + 2) is also prime”. Initially, to prove this conjecture, we can form two arithmetic sequences (A and B), with all the natural numbers, lesser than a number x, that can be primes and being each term of sequence B equal to its partner of sequence A plus 2. By analyzing the pairing process, in general, between all non-prime numbers of sequence A, with terms of sequence B, or vice versa, we note that some pairs of primes are always formed. This allow us to develop a non-probabilistic formula to calculate the approximate number of pairs of primes, p and (p + 2), that are lesser than x. The result of this formula tends to infinite when x tends to infinite, which allow us to confirm that the Twin Primes Conjecture is true. The prime numbers theorem by Carl Friedrich Gauss, the prime numbers theorem in arithmetic progressions and some axioms have been used to complete this investigation.

Proofs of Polignac Prime Conjecture, Goldbach Conjecture, Twin Prime Conjecture, Cousin Prime Conjecture, and Sexy Prime Conjecture

Authors: Stephen Marshall
Comments: 10 Pages.

This paper presents a complete and exhaustive proof of the Polignac Prime Conjecture. The approach to this proof uses same logic that Euclid used to prove there are an infinite number of prime numbers. Then we prove that if p > 1 and d > 0 are integers, that p and p+ d are both primes if and only if for integer n (see reference 1 and 2): n =(p−1)!(1/p+(−1)d(d!)/(p + d)+ 1/(p+1)+ 1/(p+d) We use this proof for d = 2k to prove the infinitude of Polignac prime numbers. Additionally, our proof of the Polignac Prime Conjecture leads to proofs of several other significant number theory conjectures such as the Goldbach Conjecture, Twin Prime Conjecture, Cousin Prime Conjecture, and Sexy Prime Conjecture. Our proof of Polignac’s Prime Conjecture provides significant accomplishments to Number Theory, yielding proofs to several conjectures in number theory that has gone unproven for hundreds of years.

Proof of Beal’s Conjecture

Authors: Stephen Marshall
Comments: 7 Pages.

Abstract: This paper presents a complete and exhaustive proof of the Beal Conjecture. The approach to this proof uses the Fundamental Theorem of Arithmetic as the basis for the proof of the Beal Conjecture. The Fundamental Theorem of Arithmetic states that every number greater than 1 is either prime itself or is unique product of prime numbers. The prime factorization of every number greater than 1 is used throughout every section of the proof of the Beal Conjecture. Without the Fundamental Theorem of Arithmetic, this approach to proving the Beal Conjecture would not be possible.

Co-Prime Gap N-Tuples that Sum to a Number and Other Algebraic Forms

Authors: Russell Letkeman
Comments: 4 Pages.

We study the spacings of numbers co-prime to an even consecutive product of primes, P_m\# and its structure exposed by the fundamental theorem of prime sieving (FTPS). We extend this to prove some parts of the Hardy-Littlewood general prime density conjecture for all finite multiplicative groups modulo a primorial. We then use the FTPS to prove such groups have gap spacings which form arithmetic progressions as long as we wish. We also establish their densities and provide prescriptions to find them.

Prime Numbers Greater Than 3 And Their Gaps Are Handed

Authors: Russell Letkeman
Comments: 3 Pages.

We build a simple recursive model for the prime numbers which at its heart is the prime sieve of Eratosthenes. We also show for prime numbers greater than 3 and their gaps posses a handedness which forbids a large range of possibilities for the choice of intervals in arithmetic progressions.

Internal Symmetries Of Sets Co-prime To A Random Product Of Prime Numbers

Authors: Russell Letkeman
Comments: 7 Pages.

We show every set modulo the product of a random collection of unique prime numbers has a palindrome in its gaps of length the minimum set minus 1. There is one more gap which is always a twin. Together the count of the gaps equals the count of the minimum modular set. This symmetry not only forces all constellations of gaps to have mirror images existing at exactly the same counts, but it also precisely identifies the center of mass (counts) of the set.

Fermat Primes to Become Criterion for the Constructibility of Regular 2^k-Sided Polygons

Authors: Pingyuan Zhou
Comments: 9 Pages. Author gives an argument for indirect connections between Fermat primes and regular 2^k-sided polygons to make Gauss-Wantzel theorem have general sense in implying connections between Fermat primes and all constructible polygons.

Abstract: Gauss-Wantzel theorem shows that regular n-sided polygons, whose number of sides contains a(distrinct) Fermat prime(s) as odd prime factor(s) of n or number of sides is power of 2, are all constructible with compass and straightedge. But of these caces, the constructibility of all regular 2^k-sided polygons is not related to Fermat primes. We discover the number of so-called root Mersenne primes Mp for p4 ( though there are no known Fermat primes Fk for k>4 ) then the constructibility of all regular 2^k-sided polygons can be indirectly explained by Fermat primes as criterion. Thus there exist direct or indirect connections between Fermat primes and all constructible regular polygons according to the theorem.

The Strong Finiteness of Double Mersenne Primes and the Infinity of Root Mersenne Primes and Near-square Primes of Mersenne Primes

Authors: Pingyuan Zhou
Comments: 14 Pages. Author presents the strong finiteness of double Mersenne primes and the infinity of root Mersenne primes and near-square primes of Mersenne primes by generalizing conjecture about primality of Mersenne number.

Abstract: In this paper we present the strong finiteness of double Mersenne primes to be a subset of Mersenne primes, the infinity of so-called root Mersenne primes to be also a subset of Mersenne primes and the infinity of so-called near-square primes of Mersenne primes by generalizing our previous conjecture about primality of Mersenne number. These results and our previous results about the strong finiteness of Fermat, double Fermat and Catalan-type Fermat primes [1] give an elementary but complete understanding for the infinity or the strong finiteness of some prime number sequences of the form 2^x±1, which all have a corresponding original continuous natural ( prime ) number sequence. It is interesting that the generalization to near-square primes of Mersenne primes Wp=2(Mp)^2-1 has brought us positive result.

Comments: 9 Pages. In this paper, author presents the strong finiteness of Fermat primes, double Fermat primes and Catalan-type Fermat primes by generalizing previous conjecture about primality of Fermat numbers to double Fermat and Catalan-type Fermat numbers.

Abstract: In this paper we present that so-called double Fermat numbers are an infinite subset of well-known Fermat numbers and so-called Catalan-type Fermat numbers are also an infinite subset of Fermat numbers as well as double Fermat primes and Catalan-type Fermat primes are all strongly finite as Fermat primes do. From it we get the same result that composite Fermat numbers, composite double Fermat numbers and composite Catalan-type Fermat numbers are all infinite.

A Conjecture on Near-square Prime Number Sequence of Mersenne Primes

Authors: Pingyuan Zhou
Comments: 4 Pages. Aothor presents a near-sguare number sequence of all Mersenne primes, which seems to be an accptable awy in searching for larger primes by known Mersenne primes themselves than the largest known Mersenne prime M57885161.

Abstract: In this paper we present a conjecture that there is a near-square prime number sequence of Mersenne primes to arise from the near-square number sequence Wp=2(Mp)^2-1 generated from all Mersenne primes Mp, in which every term is larger prime number than corresponding perfect number. The conjecture has been verified for the first few prime terms in the near-square prime number sequence and we may expect appearing of near-square prime numbers of some known Mersenne primes with large p-values will become larger primes to be searched than the largest known Mersenne prime M57885161.

Computing the Generating Function of a Series Given Its First Few Terms

Comments: 6 Pages.

We outline an approach for the computation of a good can- didate for the generating function of a power series for which only the first few coefficients are known. More precisely, if the derivative, the logarithmic derivative, the reversion, or another transformation of a given power series (even with polynomial coefficients) appears to admit a rational generating function, we compute the generating function of the original series by applying the inverse of those transformations to the rational generating function found.

Comments: 13 Pages. a better copy

We give algorithms for the computation of the d-th digit of certain transcendental numbers in various bases. These algorithms can be easily implemented (multiple precision arithmetic is not needed), require virtually no memory, and feature run times that scale nearly linearly with the order of the digit desired. They make it feasible to compute, for example, the billionth binary digit of log (2) or π on a modest work station in a few hours run time.

Let $\pi(n)$ denote the prime-counting function. In this paper we work with explicit formulas for $\pi(n)$ that are valid for infinitely many positive integers $n$, and we prove that if $n\ge 60184$ and $\ln n-\lfloor\ln n\rfloor>0.1$, then $\pi(n)$ does not divide $n$. Based on this result, we show that if $e$ is the base of the natural logarithm, $a$ is a fixed integer $\ge 11$ and $n$ is any integer in the interval $[e^{a+0.1},e^{a+1}]$, then $\pi(n)\nmid n$. In addition, we prove that if $n\ge 60184$ and $\pi(n)$ divides $n$, then $n$ is a multiple of $\lfloor\ln n-1\rfloor$ located in the interval $[e^{\lfloor\ln n-1\rfloor+1},e^{\lfloor\ln n-1\rfloor+1.1}]$.
