Abstract
Atom bond connectivity index is a topological index was defined as ABC(G) = (Formula Present) where d(v) denotes the degree of vertex v of G. Recently, M. Ghorbani et al. introduced a new version of atom-bond connectivity (ABC4) index as ABC4(G) = (Formula Present) where Su=∑vεENG(u) dv and NG(u) = {v εV(G)luv ε(G)}. In this paper we compute the fourth atom-bond connectivity index for nanocones. © 2015, National Institute of Optoelectronics. All rights reserved.
