Signless Laplacian energies of non-commuting graphs of finite groups and related results

Monalisha Sharma, Rajat Kanti Nath

The non-commuting graph of a non-abelian group $G$ with center $Z(G)$ is a simple undirected graph whose vertex set is $G\setminus Z(G)$ and two vertices $x,y$ are adjacent if $xy…
