In this paper, we introduce the subset-strong product of graphs and give a method for calculating the adjacency spectrum of this product. In addition, exact expressions for the first and second Zagreb indices of the subset-strong products of two grap

In this paper, some inequalities between the Wiener, hyper-Wiener, first Zagreb, second Zagreb, first reformulated Zagreb, second reformulated Zagreb and the general Zagreb indices of a simple graph are given. Our results improve some earlier bonds b

The Hosoya polynomial of a molecular graph G is defined as H(G,λ)=Σ{u,v}V⊆(G) λd(u,v), where d(u,v) is the distance between vertices u and v. The first derivative of H(G,λ) at λ=1 is equal to the Wiener index of G, defined as W(G)Σ{u,v}⊆V(G
