Abstract

The GA index of a molecular graph G is a recently proposed topological index defined as , deg(u) deg(v) 2 deg(u)deg(v) GA(G) Σ ∈ + = uv E where deg(u) denotes the degree of vertex u in G. In this paper the GA and Zagreb indices of some nanocones are computed.

Keywords

Nanocone, GA index.
