Fixed points of automorphisms of certain non-cyclic $p$ -groups and the dihedral group

Akhtar Abbas, Umar Hayat, Daniel López-Aguayo

Let $G = Z_{p} \oplus Z_{p^{2}}$ , where $p$ is a prime number. Suppose that $d$ is a divisor of the order of $G$ . In this paper we find the number of automorphisms of…

Commuting graphs on Coxeter groups, Dynkin diagrams and finite subgroups of $S L (2, C)$

Umar Hayat, Álvaro Nolla de Celis, Fawad Ali

For a group $H$ and a non empty subset $Γ \subseteq H$ , the commuting graph $G = C (H, Γ)$ is the graph with $Γ$ as the node set and where any $x, y \in Γ$ are joined by an edg…
