Abstract

The Narumi-Katayama index of a graph G is equal to the product
of degrees of all the vertices of G. In this paper, we examine the Narumi-Katayama index of some derived graphs such as a Mycielski graph, subdivision graphs, double graph, extended double cover graph, thorn graph, subdivision vertex join and edge join graphs.
