Certain topological indices and spectral properties of SGB-graphs of finite cyclic groups

Shrabani Das, Ahmad Erfanian, Rajat Kanti Nath

Let $L (G)$ be the set of all subgroups of a group $G$ . The subgroup generating bipartite graph $B (G)$ defined on $G$ is a bipartite graph whose vertex set is the union of…

Various spectra and energies of subgroup generating bipartite graph

Shrabani Das, Ahmad Erfanian, Rajat Kanti Nath

Let $L (G)$ be the set of all subgroups of a group $G$ . The subgroup generating bipartite graph $B (G)$ defined on $G$ is a bipartite graph whose vertex set is partitioned…

Super commuting graphs of finite groups and their Zagreb indices

Shrabani Das, Rajat Kanti Nath

Let $B$ be an equivalence relation defined on a finite group $G$ . The $B$ super commuting graph on $G$ is a graph whose vertex set is $G$ and two distinct vertices $g$ and $h$ are…

Commuting Conjugacy Class Graphs of Finite Groups and the Hansen-VukiÄeviÄ Conjecture

Shrabani Das, Rajat Kanti Nath, Yilun Shang

In this work, we compute the first and second Zagreb indices for the commuting conjugacy class graphs associated with finite groups. We identify multiple classes of finite groups w…

On a bipartite graph defined on groups

Shrabani Das, Ahmad Erfanian, Rajat Kanti Nath

Let $G$ be a group and $L (G)$ be the set of all subgroups of $G$ . We introduce a bipartite graph $B (G)$ on $G$ whose vertex set is the union of two sets $G \times G$ and…
