On the periodicity problem of residual r-Fubini sequences

Amir Abbas Asgari, Majid Jahangiri

For any positive integer $r$ , the $r$ -Fubini number with parameter $n$ , denoted by $F_{n, r}$ , is equal to the number of ways that the elements of a set with $n + r$ elements can be w…

A Novel Proof for Kimberling's Conjecture on Doubly Fractal Sequences

Matin Amini, Majid Jahangiri

A sequence is a fractal sequence if it contains itself as a proper subsequence. (The self-containment property resembles that of visual fractals) A doubly fractal sequence of integ…

Generators of Arithmetic Quaternion Groups and a Diophantine Problem

Majid Jahangiri

Let $p$ be a prime and $a$ a quadratic non-residue $mod p$ . Then the set of integral solutions of the diophantine equation $x_{0}^{2} - a x_{1}^{2} - p x_{2}^{2} + a p x_{3}^{2} = 1$ form a cocompact d…
