Spectra of generalized corona of graphs constrained by vertex subsets
R. Rajkumar, M. Gayathri
In this paper, we introduce a generalization of corona of graphs. This construction generalizes the generalized corona of graphs (consequently, the corona of graphs), the cluster o…
Spectra of -merged subdivision graph of a graph
R. Rajkumar, M. Gayathri
In this paper, we define a ternary graph operation which generalizes the construction of subdivision graph, graph, central graph. Also, it generalizes the construction of overl…
Some results on the reduced power graph of a group
R. Rajkumar, T. Anitha
The reduced power graph of a group is the graph with vertex set and two vertices and are adjacent if and only if $\left\langle v\right\rangle \sub…
Inclusion graph of subgroups of a group
P. Devi, R. Rajkumar
For a finite group , we define the inclusion graph of subgroups of , denoted by , is a graph having all the proper subgroups of as its vertices and two dis…
Toroidality and projective-planarity of intersection graphs of subgroups of finite groups
R. Rajkumar, P. Devi
Let be a group. The intersection graph of subgroups of , denoted by , is a graph with all the proper subgroups of as its vertices and two distinct vertic…
Permutability graph of cyclic subgroups
R. Rajkumar, P. Devi
Let be a group. \textit{The permutability graph of cyclic subgroups of }, denoted by , is a graph with all the proper cyclic subgroups of as its vertices and two…
