Abstract

Let G be a molecular graph. The distance between two vertices of G is the length of a shortest path connecting these two vertices. The eccentricity of a vertex u in G is the largest distance between u and any other vertex of G. In this paper, we consider some infinite families of nanostar dendrimers and compute their eccentric-connectivity index and totaleccentricity index. Furthermore, we also compute some eccentricity based Zagreb indices of these nanostar dendrimers..

Keywords

Nanostar dendrimers, Eccentric-connectivity index, Total-eccentricity index, Eccentricity based Zagreb indices.
