Abstract

Let Σ be the class of finite graphs. A topological index is a function Top from Σ in to real numbers with this property that Top(G) = Top(H), if G and H are isomorphic. Let G be a graph and e = uv be an edge of G. The GA index of G is defined as Σ∈ + = e E du dv GA(G) 2 dudv . In this paper we compute some results about this new topological index.
