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)= ( )
