On Topological Co-Indices of Polycyclic Tetrathiafulvalene and Polycyclic Oragano Silicon Dendrimers

Abstract

Topological coindices are generally utilized for quantitative structure-action relationship (QSAR) and quantitative structure property relationship (QSPR). Topological coindices are topological indices that considers the non contiguous sets of vertices. Here, we consider the accompanying some well-known topological coindices: Randic coindices, the first and second Zagreb coindices, the first and second multiplicative Zagreb coindices, the F-coindex, Atom bond connectivity Coindex, Geometric arithmetic Coindex and General Randic conidex. By utilizing graph basic investigation and deduction, we study the previously mentioned topological coindices of some synthetic atomic graphs that as often as possible show up in clinical, synthetic, and material designing. In this paper, we discuss the Polycyclic Tetrathiafulvalene and Polycyclic Oragano Silicon Dendrimers and acquire the calculation formulae of the coindices of these networks.
