Topological indices have been used to modeling biological and chemical properties of molecules in quantitive structure property relationship studies and quantitive structure activity studies. All the degree based topological indices have been defined via classical degree concept. In this paper we define a novel degree concept for a vertex of a simple connected graph: R degree. And also we defin...

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...

In this paper, we evaluate the uniqueness of several information-theoretic measures for graphs based on so-called information functionals and compare the results with other information indices and non-information-theoretic measures such as the well-known Balaban J index. We show that, by employing an information functional based on degree-degree associations, the resulting information index out...

Wiener index is a topological index based on distance between every pair of vertices in a graph G. It was introduced in 1947 by one of the pioneer of this area e.g, Harold Wiener. In the present paper, by using a new method introduced by klavžar we compute the Wiener and Szeged indices of some nanostar dendrimers.

A topological index is a characteristic value which represents some structural properties of chemical graph. We study strong double graphs and their generalization to compute Zagreb indices coindices. provide explicit computing formulas along with an algorithm generate verify the results. also find relation between these indices. 3D graphical representation are presented understand dynamics afo...
