Abstract

In this paper, our research primarily focuses on f-symmetric and unimodal properties of independence polynomials I(G∘(K_p∪K_q);x). More precisely, we prove that the independence polynomial I(G∘(K_p∪K_q);x) is unimodal for every graph G, whenever the positive integers p and q are large enough. In addition, we establish several inequalities involving the coefficients of I(G∘(K_p∪K_q);x) for arbitrary p and q.
