Abstract

Let G (V,E) be a simple graph. Then for an edge e = uv ∈ E(G), nu is the number of vertices lying closer to v than u, nv is analogously. The second geometric-arithmetic index and second atom-bond-connectivity indices are defined as GA₂(G) =Σ_uvϵE(G)(2 √ n_un_v)/(n_u +n_v) and ABC₂ =Σ uvϵE(G)√(n_u +n_v -2)/(n_un_v), respectively. In this paper, we compute the second versions of geometric arithmetic and atom bond connectivity indices of Titania carbon Nanotubes TiO₂(m,n).
