Topological indices are numeric values associated with a graph and characterize its structure. There various topological in theory such as degree-based, distance-based, counting-related indices. Among these indices, degree-based very interesting studied well literature. In this work, we the generalized form of harmonic, geometric-arithmetic, Kulli–Basava power-sum-connectivity index for special...

Let G and H be connected graphs. The tensor product G + H is a graph with vertex set V(G+H) = V (G) X V(H) and edge set E(G + H) ={(a , b)(x , y)| ax ∈ E(G) & by ∈ E(H)}. The graph H is called the strongly triangular if for every vertex u and v there exists a vertex w adjacent to both of them. In this article the tensor product of G + H under some distancebased topological indices are investiga...

A real-number to molecular structure mapping is a topological index. It graph invariant method for describing physico-chemical properties of structures specific substances. In that article, We examined pentacene’s chemical composition. The research on the subsequent indices reflected in our paper, we conducted an analysis several including general randic connectivity index, first zagreb sum-con...

We define topological and analytic indices in R/Z K-theory and show that they are equal.
