Abstract

In this paper, we compute the nullity and number of Kekulé structures in a class of hetrofuctional dendrimers (HFD)ei. When there is no Kekulé structure in a dendrimer, we find the size of a maximum matching in it. Furthermore, we compute the first and fourth version of atom-bond connectivity index, first and fifth version of geometric-arithmetic index and Randić index of this dendrimer..

Keywords
