Characteristic Polynomial of Power Graphs on Direct Product of Any Two Finite Cyclic Groups

Komal Kumari, Pratima Panigrahi

The power graph $P (G)$ of a group $G$ is defined as the simple graph with vertex set $G$ , and where two distinct vertices $x$ and $y$ are joined by an edge if and only if…

Universal adjacency spectrum of (proper) power graphs and their complements on some groups

Komal Kumari, Pratima Panigrahi

The power graph $P (G)$ of a group $G$ is an undirected graph with all the elements of $G$ as vertices and where any two vertices $u$ and $v$ are adjacent if and only if $…
