Abstract

Let ∑ be the class of finite graphs. A topological index is a function Top from ∑ into 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 e E 2 dudv GA(G) du dv∈= +∑ . In this paper we compute some results about this new topological index..
