Abstract

Let G be a simple connected graph. If e=uv is an edge of G and nu(e) is the number of vertices closer to u than v and nv(e) is the number of vertices closer to v than u, then the second geometric-arithmetic index (GA2) of G are defined as GA2(G)=  In this paper GA2 index of Circumcoronene series of benzenoid Hk (k≥1), are computed for the first time by using Cut Method and its Orthogonal Cuts.

Keywords: Molecular graphs, topological index, geometric-arithmetic index, cut method, orthogonal cut, circumcoronene series of benzenoid
