The Automorphism Group of the Spectral Incidence Graph over Finite Fields

Ali Majidinya

Let $F_{q}$ be a finite field with $q$ elements and let $V_{0} = F_{q}^{n}$ be the $n$ -dimensional vector space over $F_{q}$ , for an integer $n \geq 2$ . We in…

Automorphisms of linear functional graphs over vector spaces

Ali Majidinya

Let $F_{q}$ be a finite field with $q$ elements, $n \geq 2$ a positive integer, $V_{0}$ a $n$ -dimensional vector space over $F_{q}$ and $T_{0}$ the set of…

Sum-Essential Graphs of Modules

Jerzy Matczuk, Ali Majidinya

The sum-essential graph $S_{R} (M)$ of a left $R$ -module $M$ is a graph whose vertices are all nontrivial submodules of $M$ and two distinct submodules are adjacent iff th…

A note on co-maximal graph of non-commutative rings

S. Akbari, M. Habibi, A. Majidinya +1

Let $R$ be a ring with unity. The graph $Γ (R)$ is a graph with vertices as elements of $R$ , where two distinct vertices $a$ and $b$ are adjacent if and only if $R a + R b = R$ . Let $Γ_2(…
