The minimum harmonic index for bicyclic graphs with given diameter

A. Abdolghafourian, Mohammad A. Iranmanesh

The harmonic index of a graph $G$ , is defined as the sum of weights $\frac{2}{d ( u ) + d ( v )}$ of all edges $uv$ of $G$ , where $d (u)$ is the degree of the vertex $u$ in $G$ . In this pap…

The Divisibility Graph of finite groups of Lie Type

Adeleh Abdolghafourian, Mohammad A. Iranmanesh, Alice C. Niemeyer

The Divisibility Graph of a finite group $G$ has vertex set the set of conjugacy class lengths of non-central elements in $G$ and two vertices are connected by an edge if one divid…

On divisibility graph for simple Zassenhaus groups

Adeleh Abdolghafourian, Mohammad A. Iranmanesh

The divisibility graph $D (G)$ for a finite group $G$ is a graph with vertex set $cs (G) ∖ {1}$ where $cs (G)$ is the set of conjugacy class sizes of $G$ . Two vertices $a$ a…

Divisibility graph for symmetric and alternating groups

Adeleh Abdolghafourian, Mohammad A. Iranmanesh

Let $X$ be a non-empty set of positive integers and $X^{*} = X ∖ {1}$ . The divisibility graph $D (X)$ has $X^{*}$ as the vertex set and there is an edge connecting $a$ and $b$ wi…
