Some S-degree Based Topological Indices of Silicates (SiO2) Layer
A topological index is a graph invariant, which is generated as a real number from a set of finite graphs. A large number of topological indices have been developed based on vertex degree, eccentricity, etc. and studied extensively. In this paper we propose a new version of the inverse sum indeg index (ISI), sum-connectivity index (SCI), redefined third Zagreb index and (a,b)- Zagreb index based on S-degrees of vertices a graph and discuss them in connection with SiO2 layer structure in a graph theoretic perspective.
