Abstract

Let G is an arbitrary simple, connected, graph, wit h the vertex set V(G) and edge set E(G). In chemica l graph theory, we have many invariant polynomials and topo logical indices for a molecular graph, with applied in chemical and nano science and vice versa. Topological indice s are numerical parameters of a molecular graph G w hich characterize its topology.
