Abstract

The GA index is a topological index was defined as 2 ( ) ( ) ( ) uv E ( ) ( ) d u d v GA G d u d v ∈ = + Σ , in which degree of a vertex u denoted by d(u). Atom bond connectivity index is another topological index defined as ( ) ( ) ( ) 2 uv E ( ) ( ) ABC G d u d v d u d v ∈ + − = Σ . In this paper we compute these topological indices for two types of nanocones.

Keywords

Topological Index, GA and ABC Indices, Nanocones.
