On General Formulas for Generating Sequences of Pythagorean Triples Ordered by C-B

Authors: Eduardo Calooy Roque
Comments: 8 Pages.

General formulas for generating sequences of Pythagorean triples ordered by c-b are studied in this paper. As computational proof, tables were made with a C++ script showing Pythagorean triples ordered by c-b and included as text files and screenshots. Furthermore, to enable readers to check and verify them, the C++ script which will interactively generate tables of Pythagorean triples from the computer console command line is attached. It can be run in Cling and ROOT CINT C/C++ interpreters or compiled.

On the Interval $[n,9(n+3)/8]$

Authors: Germán Paz
Comments: 75 Pages. The result in this paper (as well as some other results) has been published in ''General Mathematics Notes''. Journal reference: On the Interval [n,2n]: Primes, Composites and Perfect Powers, General Mathematics Notes, 15(1) (2013), 1-15.

In this paper we prove that the interval $[n,9(n+3)/8]$ contains at least one prime number for every positive integer $n$. In order to achieve our goal, we use a result by Pierre Dusart and we also do manual calculations.

Números Primos de Sophie Germain, Demostración de su Infinitud

Authors: Germán Paz
Comments: 29 Pages. In Spanish. // En español. - Un resumen de este trabajo está disponible en http://www.abcdatos.com/tutoriales/tutorial/v2200.html. Dicho resumen fue realizado por Carlos Giraldo Ospina (Lic. Matemáticas, USC, Cali, Colombia).

En este trabajo se propone una demostración de que existen infinitos números primos de las formas $2p+i$ y $2p-i$, con $p$ primo e $i$ entero positivo impar. Pruebas de teoremas más generales se proponen en los artículos viXra:1202.0061 y viXra:1202.0063. // In this paper we propose a proof that there exist infinitely many prime numbers of the forms $2p+i$ and $2p-i$, where $p$ is a prime number and $i$ is a positive odd integer. Proofs of more general theorems are proposed in the articles viXra:1202.0061 and viXra:1202.0063.

A New Method to Express Sums of Power of Integers as a Polynomial Equation

Authors: Nasser Almismari
Comments: 9 Pages.

This is a new method to express The power sums of (n^m) as a (m+1)th-degree polynomial equation of n, there is some methods like "Faulhaber's formula" and others gives the solution of the power sums. nevertheless my method is doing the same but it does not depend on Bernoulli numbers or integrals as it is a simple algebraic way giving a polynomial equation and proved in a elementary algebraic logic.

Fermat Last Theorem (3)

Authors: Chun-Xuan Jiang
Comments: 4 Pages.

Using complex hyperbolic functions of order 4m with 4m-1 variables we prove Fermat last theorem for exponents 4p and p ,where p is an odd prime.We rediscover the Fermat proof. The proof of FLT must be direct.But indirect proof of FLT is disbelieving.

On the Fibonacci Numbers, the Koide Formula, and the Distribution of Primes

Authors: J. S. Markovitch
Comments: 71 Pages.

The Koide formula from physics is modified for use with the reciprocals of primes found in the intervals defined by the Fibonacci numbers. This formula's resultant values are found to alternate lower, higher, lower, higher, etc. from the interval (5,8] to the interval (514229,832040]. This pattern, inverted, is also shown to occur when the corresponding results are computed for non-primes.
