Some topological indices of dendrimers

摘要

There are immense applications of graph theory in chemistry and in the study of molec-ular structures, and after that, it has been increasing exponentially. Molecular graphs have points (vertices) representing atoms and lines (edges) that represent bonds between atoms. In this paper, we study the molecular graph of porphyrin, propyl ether imine, zinc-porphyrin and poly dendrimers and analyzed its topological properties. For this purpose, we have computed topological indices, namely the Albertson index, the sigma index, the Nano-Zagreb index, the first and second hyper F-indices of porphyrin, propyl ether imine, zinc-porphyrin and poly dendrimers.
