abstract = {Topological indices are numerical parameters of a molecular graph G which characterize its topology. On the other hands, computing the connectivity indices of molecular graphs is an important branch in chemical graph theory. Therefore, we compute First Zagreb index Zg 1(G)= uv E (G ) ( u v ), d d ∈ Σ + Second Zagreb index Zg 2(G)= ( ) uv E (G ) u v d d ∈ Σ × and their polynomials Zg1(G,x)= ( ) d u dv uv E G x ∈ Σ + and Zg2(G,x)= ( ) d udv uv E G x ∈ Σ for two famous families of nanotubes “HAC 5C6C7[p,q]” and “HAC5C7[p,q]”. },
