Automorphism group of the reduced power (di)graph of a finite group

T. Anitha, R. Rajkumar

We describe the full automorphism group of the directed reduced power graph and the undirected reduced power graph of a finite group. We compute the full automorphism groups of the…

Coprime graph of subgroups of a group

R. Rajkumar, P. Devi

Let $G$ be a group. We define the coprime graph of subgroups of $G$ , denoted by $P (G)$ , is a graph whose vertex set is the set of all proper subgroups of $G$ , and two dist…

Intersection graph of cyclic subgroups of groups

R. Rajkumar, P. Devi

Let $G$ be a group. The intersection graph of cyclic subgroups of $G$ , denoted by $I_{c} (G)$ , is a graph having all the proper cyclic subgroups of $G$ as its vertices and tw…

Classification of finite groups with toroidal or projective-planar permutability graphs

R. Rajkumar, P. Devi, Andrei Gagarin

Let $G$ be a group. The permutability graph of subgroups of $G$ , denoted by $Γ (G)$ , is a graph having all the proper subgroups of $G$ as its vertices, and two subgroups are adjacen…
