Abstract
Suppose G is a simple graph and c k = c k (G) denotes the number of complete subgraphs of size k in G. Then the dependence polynomial of G is defined as f G (x) = 1−c1x+c2x2−c3x 3+⋯+(−1)n xn, 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.
