Degree based topological indices of sanidic polyamides

2019
Sanidic polyamides are special polymers with many applications  in textile and clothing industries. In this paper, we calculate several degree based topological graph indices of the sanidic polyamides as these values helps to determine several chemical and physicochemical properties of these polyamides.

On degree based topological indices of bridge graphs

Journal of Discrete Mathematical Sciences and Cryptography, 2020
In 2009, T. Mansour, M. Schork, introduce the concept of bridge graphs. A bridge graph B(G 1, G 2, … , Gm ) = B(G 1, G 2, … , Gm ; v 1, v 2, … , vm ) of with respect to the vertices is the graph ob...

Calculating Degree Based Multiplicative Topological Indices of Alcohol

SSRN Electronic Journal, 2018
Description the entire structure of a graph by a mathematical quantity called topological index. These topological indices are categorized on the basis of their logical roots from topological invariants. Degree based topological indices depends upon the degree of the vertex.
