Abstract

Let G be a simple graph with vertex set V (G). The common neighborhood graph or
congraph of G, denoted by con(G), is a graph with vertex set V (G), in which two vertices
are adjacent if and only if they have at least one common neighbor in G. We compute the
congraphs of some composite graphs. Using these results, the congraphs of several special
graphs are determined.
