Neighborhood Degree Sum-based Molecular Indices and Their Comparative Analysis of Some Silicon Carbide Networks

Abstract Topological indices of a molecular graph are numeric quantities that characterize its numerous physico-chemical properties, chemical reactivities and biological activities. The neighborhood M-polynomial is productive for discovering neighborhood degree sum-based topological indices. This article deals with computing the neighborhood M-polynomial of silicon carbide networks Si 2 C 3 - I p , q , Si 2 C 3 - II p , q and Si 2 C 3 - III p , q , and hence examining some standard neighborhood degree sum-based topological indices for the aforementioned networks. The obtained results are analyzed graphically. Moreover, a comparative study of the outcomes with some well-established degree-based topological indices of the silicon carbide networks is executed.
