• Topological index
• GA index
• GA(4) index
• Hamiltonian graphs

The geometric-arithmetic index is another topological index was defined as GA(G) = Sigma(uv eE) 2 root d(u)d(v)/d(u) + d(v), in which degree of vertex u denoted by d(u). We now define a new version of GA index as GA4(G) = Sigma(e E(G)) 2 root epsilon(u)epsilon(v)/epsilon(u)+epsilon(v), where epsilon(u) is the eccentricity of vertex u. In this paper we compute these topological indices for fullerene graphs.
