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…
