Abstract

Let Σ be the class of finite graphs. A topological index is a function Top from Σ into real numbers with this property that Top(G) = Top(H), if G and H are isomorphic. Obviously, the number of vertices and the number of edges are topological index. In this paper we compute two classes of GA indices of nanostructures.

Keywords

Topological indices, Automorphism group, Fullerene graph, Nanotori.
