(Total) Perfect codes in (extended) subgroup sum graphs

Xuanlong Ma, Yuefeng Yang, Liangliang Zhai

Given a finite group $G$ with identity $e$ and a normal subgroup $H$ of $G$ , the subgroup sum graph $Γ_{G, H}$ (resp. extended subgroup sum graph $Γ_{G, H}^{+}$ ) of $G$ with respect to…

Forbidden subgraphs on conjugacy class graphs of groups

Papi Ray, Sonakshee Arora, Xuanlong Ma

Let $G$ be a finite group. The commuting (resp. nilpotent) conjugacy class graph $Γ_{C C C} (G)$ (resp. $Γ_{N C C} (G)$ ) of $G$ is a simple graph whose vertex set consists of all non-cen…
