We first prove a weak form of Fermat's Last Theorem; this unique lemma is key to the entire proof. A corollary and lemma follow inter-relating Pythagorean and Fermat solutions. Finally, we prove Fermat's Last Theorem.

This paper presents a method of calculating powers and sums of powers using binomial coefficients. The method involves finding analogues of Pascal's triangle for each power and then showing that powers and sums of powers are the sums of binomial coefficients multiplied by constants. The constants are unique for each power. This paper presents a general idea and not a formal proof.

We discuss the asymptotics of the sum $\sum_{k=1}^{m} e^{ \frac{{\ln(k)}^n}{k} }-1$ for $n \geq 0 $. Our main interest is to show the asymptotics of this sum and show expressions for the constants tied to the asymptotics of the sum as well as in particular show the properties of the constants associated with the sum.

Positive integers which can operate to 1 by the set operational rule of the conjecture and positive integers got via contrary operations of the set operational rule are one-to-one correspondence unquestionably. In this article, we classify positive integers to prove the Collatz conjecture by the mathematical induction via operations of substep according to confirmed two theorems plus a lemma in advance.

In this paper, some properties of k Fibonacci and k Lucas numbers are derived and proved by using matrices S and M. The identities we proved are not encountered in the k Fibonacci
and k Lucasnumber literature.

In this paper we defined general matrices Mk(n,m),
Tk,n and Sk(n,m) for k-Fibonacci number. Using these matrices we find some new summation properties for k-Fibonacci and k-Lucas

Coupled Fibonacci sequences involve two sequences of integers in which the elements of one sequence are part of the generalization of the other and vice versa. K. T. Atanassov was first introduced coupled Fibonacci sequences of second order in additive form. In this paper, I present some properties of multiplicative coupled Fibonacci sequences of fourth order under two specific schemes.

Coupled Fibonacci sequences involve two sequences of integers in which the elements of one sequence are part of the generalization of the other and vice versa. K. T. Atanassov was first introduced coupled Fibonacci sequences of second order in additive form. There are 32 different schemes of generalization for the Fibonacci sequences of fifth order in the case of two sequences [1]. I introduce their recurrent formulas below.

There are 8 different schemes of generalization for the Tribonacci sequences in the case of two sequences & there are 16 different schemes of generalization for the Tetranacci sequences in the case of two sequences.

By defining a function for a linear equation (of slope-intercept form) to be a composite generator, I am able to show that a subset of odd-value slopes must always have even solutions. I apply this function to generate a parity truth table for any perfect square interval that demonstrates the unequal cardinality of the subsets of odd and even composites. Using elementary set theory I demonstrate that this inequality is deterministic, eliminating the possibility of a prime-free interval. This method successfully attacks Legendre's conjecture, providing a logical-conceptual framework for a formal proof.

In this paper we consider the Riemann hypothesis (RH) by the Euler function and the primorial numbers. We find a new sufficient condition for the RH from well known Robin theorem and prove that the condition holds unconditionally.

A formula giving the $n$:th number of a sequence defined by a recursion formula plus initial value is deduced using generating functions. Of particular interest is the possibility to get an exact expression for the n:th term by means a recursion formula of the same type as the original one. As for the sequence itself it is of some interest that the original recursion is non-linear and the fact that the sequence grows very fast, the number of digits increasing more or less exponentially. Other sequences with the same rekursion span can be treated similarly.

This paper presents a “formula” (more or less) for prime numbers in a specific interval. This formula is then used to partially prove the Goldbach conjecture and the twin primes conjecture. The proofs are incomplete however and have not been reviewed by anyone.
