Hosoya properties of power graphs over certain groups

Yogendra Singh, Anand Kumar Tiwari, Fawad Ali

The power graph denoted by $P (G)$ of a finite group $G$ is a graph with vertex set $G$ and there is an edge between two distinct elements $u…

On the $A_{α}$ and $R D_{α}$ matrices over certain groups

Yogendra Singh, Anand Kumar Tiwari, Fawad Ali

The power graph $G = P (Ω)$ of a finite group $Ω$ is a graph with the vertex set $Ω$ and two vertices $u, v \in Ω$ form an edge if and only if one is an integral power of the other.…

On the Spectral properties of power graphs over certain groups

Yogendra Singh, Anand Kumar Tiwari, Fawad Ali

The power graph $P (Ω)$ of a group $Ω$ is a graph with the vertex set $Ω$ such that two distinct vertices form an edge if and only if one of them is an integral power of the other.…

On the power graph of a certain gyrogroup

Yogendra Singh, Anand Kumar Tiwari, Fawad Ali +1

The power graph $P (G)$ of a group $G$ is a simple graph with the vertex set $G$ such that two distinct vertices $u, v \in G$ are adjacent in $P (G)$ if and only if $u^{m} = v$ or $v^m…

2-semi-equivelar maps on the torus and Klein bottle with few vertices

Anand Kumar Tiwari, Yogendra Singh, Amit Tripathi

The $k$ -semi equivelar maps, for $k \geq 2$ , are generalizations of maps on the surfaces of Johnson solids to closed surfaces other than the 2-sphere. In the present study, we dete…
