On the structure of the power graph and the enhanced power graph of a group
Let $ G $ be a group. The\emph {power graph} of $ G $ is a graph with the vertex set $ G $,
having an edge between two elements whenever one is a power of the other. We …

J Dutta, RK Nath - arXiv preprint arXiv:1604.07133, 2016 - arxiv.org
In this paper, we initiate the study of spectrum of the commuting graphs of finite non-abelian
groups. We first compute the spectrum of this graph for several classes of finite groups, in …
