Abstract

The GA4 index is a topological index was defined as 4 2 ε( )ε( ) ( ) uv E ε( ) ε( ) u v GA G u v ∈ = + Σ , in which eccentricity of vertex u denoted by ε(u). Recently some classes of GA index were introduced. In this paper we compute the GA4 index of nanostar dendrimers..

Keywords

Topological index, Nanostar dendrimer.
