On enhanced power graphs of finite groups

open access: yesJournal of Algebra and Its Applications, 2018
Given a group [Formula: see text], the enhanced power graph of [Formula: see text], denoted by [Formula: see text], is the graph with vertex set [Formula: see text] and two distinct vertices [Formula: see text] and [Formula: see text] are edge connected in [Formula: see text] if there exists [Formula: see text] such that [Formula: see text] and ...

On enhanced power graphs of certain groups

Discrete Mathematics, Algorithms and Applications, 2020
The enhanced power graph [Formula: see text] of a group [Formula: see text] is a simple undirected graph with vertex set [Formula: see text] and two distinct vertices [Formula: see text] are adjacent if both [Formula: see text] and [Formula: see text] belongs to same cyclic subgroup of [Formula: see text].

Enhanced power graphs are weakly perfect [PDF]

open access: possibleAustralas. J Comb., 2023
Summary: A graph is weakly perfect if its clique number and chromatic number are equal. We show that the enhanced power graph of a finite group \(G\) is weakly perfect: its clique number and chromatic number are equal to the maximum order of an element of \(G\). The proof requires a combinatorial lemma. We give some remarks about related graphs.
