The Minimal (Edge) Connectivity of Some Graphs of Finite Groups

Abstract

In this paper, we classify all the finite groups $G$ such that the commuting graph ${\Gamma }_C(G)$, order-sum graph ${\Gamma }_{OS}(G)$ and non-inverse graph ${\Gamma }_{NI}(G)$ are minimally edge connected graphs. We also classify all the finite groups $G$ for that, these graphs are minimally connected. We also classify some groups for that the co-prime graph ${\Gamma }_{CP}(G)$ has minimal edge connectedness. In final part, we classify all the finite groups $G$ for that co-prime graph ${\Gamma }_{CP}(G)$ is minimally connected.
