Atom Bound Connectivity, Zagreb, Sombor, Nirmala and Harmonic Indices of Dendrimers

Abstract

A nanostar is a very small molecule ranging in size from 1-100 nanometers. It is typically composed of materials such as polymers, silica and others. Nanostars are of great significance in various fields, including drug technology, energy technology and other applications. The topological index is a numerical depiction of a molecular structure. Within chemical graphs, the atoms and the chemical bonds connecting them are symbolized by vertices and edges, respectively. Topological indices help to predict the topological properties of nanostar dendrimers, such as molecular weight and size. In this article, we  computed the first Zagreb index, the second Zagreb Index, the third Zagreb  index,   Sombor index, ABC index, Nirmala index and Harmonic index of two new families of nanostar dendrimers such as   is also known as aminoisophthalate diester monomer and  known as Poly (amidoamine).
