On graphs with equal domination and total domination numbers

Sudip Bera

For a graph $G$ without isolated vertices, $γ (G) \leq γ_{t} (G) \leq 2 γ (G)$ . While graphs attaining $γ (G) = γ_{t} (G)$ have been studied extensively, a complete structural description in the sm…

On the finite group whose proper enhanced power graph is claw-free

Sudip Bera, Andrea Lucchini

Let $G$ be a finite group. The \emph{enhanced power graph} of $G$ , denoted by $E (G)$ , is the graph with vertex set $G$ in which two vertices $u$ and $v$ are adjacent if a…
