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…
