On adjacency and (signless) Laplacian spectra of centralizer and co-centralizer graphs of some finite non-abelian groups

Jharna Kalita, Somnath Paul

Let $G$ be a finite non abelian group. The centralizer graph of $G$ is a simple undirected graph $Γ_{ce n t} (G)$ , whose vertices are the proper centralizers of $G$ and two vertices a…

A note on the distance spectra of co-centralizer graphs

Jharna Kalita, Somnath Paul

Let $G$ be a finite non abelian group. The centralizer graph of $G$ is a simple undirected graph $Γ_{ce n t} (G)$ , whose vertex set consists of proper centralizers of $G$ and two vert…

On the distance & distance (signless) Laplacian spectra of non-commuting graphs

Jharna Kalita, Somnath Paul

Let $Z (G)$ be the centre of a finite non-abelian group $G .$ The non-commuting graph of $G$ is a simple undirected graph with vertex set $G ∖ Z (G),$ and two vertices $u$ and…
