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 $(H_{1}, H_{2})$ -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, $R -$ graph, central graph. Also, it generalizes the construction of overl…
