Abstract

Suppose G is a simple graph and ck = ck(G) denotes the number of complete subgraphs of size k in G. Then the dependence polynomial of G is defined as fG(x) = 1−c1x+c2x2−c3x3+⋯+(−1)nxn, where n is the size of the largest complete subgraph in G. In this paper, exact formulas for dependence polynomial of some graph operations are presented.
