The power index of a graph

Xuanlong Ma, Min Feng, Kaishun Wang

The {\em power index} $Θ (Γ)$ of a graph $Γ$ is the least order of a group $G$ such that $Γ$ can embed into the power graph of $G$ . Furthermore, this group $G$ is {\em $Γ$ -optimal}…

The strong metric dimension of the power graph of a finite group

Xuanlong Ma, Min Feng, Kaishun Wang

We characterize the strong metric dimension of the power graph of a finite group. As applications, we compute the strong metric dimension of the power graph of a cyclic group, an a…

Finite groups with star-free noncyclic graphs

Xuanlong Ma, Gary L. Walls, Kaishun Wang

For a finite noncyclic group $G$ , let $\Cyc(G)$ be a set of elements $a$ of $G$ such that $⟨ a, b ⟩$ is cyclic for each $b$ of $G$ . The noncyclic graph of $G$ is a graph…
