On finite groups whose coprime graph is a divisor graph

Xuanlong Ma, Liangliang Zhai, Nan Gao +1

In this paper, we first characterize which generalized lexicographic products are divisor graphs. As applications, we show that power graphs, reduced power graphs and order graphs…

The diameter and dominating sets of the difference graph of a nilpotent group

Xuanlong Ma, Samir ZahiroviÄ, Katarina Å½igeroviÄ

Given a finite group $G$ , the difference graph of $G$ , denoted by $D (G)$ , is the difference of the enhanced power graph of $G$ and the power graph of $G$ , with all isolat…

Forbidden subgraphs on conjugacy class graphs of groups

Papi Ray, Sonakshee Arora, Xuanlong Ma

Let $G$ be a finite group. The commuting (resp. nilpotent) conjugacy class graph $I^_{C C C} (G)$ (resp. $I^_{N C C} (G)$ ) of $G$ is a simple graph whose vertex set consists of all non-c…
