Computing topological indices of some hyper-branched macromolecules



  1. School of Natural Sciences, National University of Sciences and Technology, Sector H-12, Islamabad, Pakistan


In this paper we calculate the number of Kekulé structures, anti-Kékule number and nullity of some families of nanostar dendrimers. In case when the nanostar dendrimer has no Kekulé structure, we give the size of a maximum matching in it. Furthermore, we investigate the first and fourth version of atom-bond connectivity index and first and fifth version of geometric-arithmetic index for these nano-structures..
