Some polynomials and degree-based topological indices of molecular graph and line graph of Titanium dioxide nanotubes

Journal of Information and Optimization Sciences
Graph polynomials based on distance and degree are helpful and necessary because they contain much information about topological indices. In this article, the general inverse sum indeg index and the generalized inverse sum indeg polynomials are ...

On the QSPR Models of some Anti-Malaria Drugs using some Reversed Degree-Based Topological Indices

Lafia Journal of Scientific and Industrial Research
A topological index is a real number obtained from the chemical structure of a molecular graph that can be used to predict the physiochemical and biological properties of chemical compounds like drugs and benzene structures. This study aimed at proposing

Neighborhood Degree Based Topological Indices of Nanotube via Direct and NM‐Polynomial

International Journal of Quantum Chemistry
The analysis of various chemical structures can be done by using topological indices (TI), graph polynomials, and other useful tools that graph theory offers. The mathematical entries called TI are subtracted from the chemical structure. In this article,

Computing Degree-Based Topological Indices of Polyhex Nanotubes

2016
Recently, Shigehalli and Kanabur [20] have put forward for new degree based topological indices, namely Arithmetic-Geometric index (AG1 index), SK index, SK1 index and SK2 index of a molecular graph G. In this paper, we obtain the explicit formulae of these indices for Polyhex Nanotube without the aid of a computer.

Computing degree based topological indices for bulky and normal polymers

International Journal of Quantum Chemistry
A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. The bulky and normal polymers are graphs of aromatic organic compounds.
