Goldbach's conjecture on the expression of odd numbers and some examples

A simple proof for Last Fermat Theorem when n=4 in Gaussian Integers

A simple geometric proof for the formula \(1 + 3 + 5 + \ldots + (2n - 1) + (2n + 1) + (2n - 1) + \ldots + 5 + 3 + 1 = n^2 + (n + 1)^2\)

The graph obtained by constructing an edge between each pair of primes with difference a power of 2 is not connected.

An interesting unusual visual and rigorous proof of Fermat`s Little Theorem, with unusual generalizations

This article presents an algebraic proof of the primitive root theorem.

If two elements in a ring are multiples of each other, are they necessarily unit multiples? In general, the answer is no; it is yes for the integers mod \(n\).

The author proves Fermat's little theorem using iteration of functions.

The author constructs infinitely many integer solutions to the title equation \(X^n + Y^n = Z^{n+1}\).
