Abstract

Given a simple graph AA on a group GG and an equivalence relation BB on GG, the BB super AA graph is defined as a simple graph, whose vertex set is GG and two vertices gg, hh are adjacent if either they are in the same equivalence class or there exist g[g]g^{\prime} \in[g] and h[h]h^{\prime} \in[h] such that gg^{\prime} and hh^{\prime} are adjacent in AA. In the literature, the BB super AA graphs have been investigated by considering AA to be either power graph, enhanced power graph, or commuting graph and BB to be an equality, order or conjugacy relation. In this paper, we investigate the Sombor spectrums of these BB super AA graphs for certain non-abelian groups, viz. the dihedral group, generalized quaternion group and the semidihedral group, respectively.
