Abstract

The power graph G=P(Ω)G = P(\Omega) of a finite group Ω\Omega is a graph with the vertex set Ω\Omega and two vertices u,vΩu, v \in \Omega form an edge if and only if one is an integral power of the other. Let D(G)D(G), A(G)A(G), RT(G)RT(G), and RD(G)RD(G) denote the degree diagonal matrix, adjacency matrix, the diagonal matrix of the vertex reciprocal transmission, and Harary matrix of the power graph GG respectively. Then the AαA_{\alpha} and RDαRD_{\alpha} matrices of GG are defined as Aα(G)=αD(G)+(1α)A(G)A_{\alpha}(G) = \alpha D(G) + (1-\alpha)A(G) and RDα(G)=αRT(G)+(1α)RD(G)RD_{\alpha}(G) = \alpha RT(G) + (1-\alpha)RD(G). In this article, we determine the eigenvalues of AαA_{\alpha} and RDαRD_{\alpha} matrices of the power graph of group G=s,r:r2kp=s2=e, srs1=r2k1p1 \mathcal{G} = \langle s,r \, : r^{2^kp} = s^2 = e,~ srs^{-1} = r^{2^{k-1}p-1}\rangle. In addition, we calculate its distant and detotar distance degree sequences, metric dimension, and strong metric dimension.
