Character graphs with diameter three

Mahdi Ebrahimi

For a finite group $G$ , let $Δ (G)$ denote the character graph built on the set of degrees of the irreducible complex characters of $G$ . In this paper, we show that if the diameter…

The character graph of a finite group is perfect

Mahdi Ebrahimi

For a finite group $G$ , let $Δ (G)$ denote the character graph built on the set of degrees of the irreducible complex characters of $G$ . In graph theory, a perfect graph is a graph…
