Characterisations of finite groups with exponent $q$ via their power graphs

Aditya Singh, Anmol chugh, Yogendra Singh +1

The power graph $P (G)$ of a finite group $G$ is the graph with vertex set $G$ and edge set $E(P(G))=\{uv:\ u,v \in G,\ u \neq v,\ u \in \langle v \rangle \ \text{or}\ v \in \langle…

Spectral Properties of Power Graphs of Metacyclic Groups

Aditya Singh, Yogendra Singh, Anand Kumar Tiwari

For a group $I^c ◯$ , the associated power graph $P (I^c ◯)$ is defined as the graph whose vertices are the elements of $I^c ◯$ , with two distinct vertices $u, v \in I^c ◯$ being adjacent if eithe…

$R D_{I^} \pm$ -Spectra of Joined Union Graphs with Applications to Power Graphs of Finite Groups

Aditya Singh, Yogendra Singh, Anand Kumar Tiwari

The \emph{generalized reciprocal distance matrix} of a graph $G$ , denoted by $R D_{I^} \pm (G)$ , is defined as $RD_Î±(\mathscr{G})=Î±\,RT_r(\mathscr{G})+(1-Î±)\,RD(\mat…
