Characterizing finite groups whose enhanced power graphs have universal vertices

David G. Costanzo, Mark L. Lewis, Stefano Schmidt +2

Let $G$ be a finite group and construct a graph $Δ (G)$ by taking $G ∖ {1}$ as the vertex set of $Δ (G)$ and by drawing an edge between two vertices $x$ and $y$ if $\langle x…

The cyclic graph (deleted enhanced power graph) of a direct product

David G. Costanzo, Mark L. Lewis, Stefano Schmidt +2

Let $G$ be a finite group. Define a graph on the set $G^{#} = G ∖ {1}$ by declaring distinct elements $x, y \in G^{#}$ to be adjacent if and only if $\langle x,y\rangle…
