On ve-degree- and ev-degree-based topological properties of crystallographic structure of cuprite Cu2O

open access: yesOpen Chemistry, 2021
In the study of chemical graph theory, an enormous number of research analyses have confirmed that the characteristics of chemicals have a nearby connection with their atomic structure.

Comparative Study of Prism Octahedron Network via Eccentric Invariants

open access: yesJournal of Chemistry, 2023
Topological indices are empirical features of graphs that characterize the topology of the graph and, for the most part, are graph independent. An important branch of graph theory is chemical graph theory.

M-polynomial and topological indices of zigzag edge coronoid fused by starphene

open access: yesOpen Chemistry, 2020
Chemical graph theory is a subfield of graph theory that studies the topological indices for chemical graphs that have a good correlation with chemical properties of a chemical molecule.

M-Polynomials and Topological Indices for Line Graphs of Chain Silicate Network and H-Naphtalenic Nanotubes

open access: yesJournal of Mathematics, 2021
Graph theory has provided a very useful tool, called topological index, which is a number from the graph M with the property that every graph N isomorphic to M value of a topological index must be same for both M and N.

Multiplicative Topological Properties on Degree Based for Fourth Type of Hex-Derived Networks

open access: yesJournal of Function Spaces, 2022
Chemical graph theory is a subfield of graph theory that uses a molecular graph to describe a chemical compound. When there is at least one connection between the vertices of a graph, it is said to be connected.

On Computation Degree-Based Topological Descriptors for Planar Octahedron Networks

open access: yesJournal of Mathematics, 2021
A molecular graph is used to represent a chemical molecule in chemical graph theory, which is a branch of graph theory. A graph is considered to be linked if there is at least one link between its vertices.

A network dynamics approach to chemical reaction networks [PDF]

open access: yes, 2015
A crisp survey is given of chemical reaction networks from the perspective of general nonlinear network dynamics, in particular of consensus dynamics. It is shown how by starting from the complex-balanced assumption the reaction dynamics governed by mass

Edge Metric and Fault-Tolerant Edge Metric Dimension of Hollow Coronoid

open access: yesMathematics, 2021
Geometric arrangements of hexagons into six sides of benzenoids are known as coronoid systems. They are organic chemical structures by definition. Hollow coronoids are divided into two types: primitive and catacondensed coronoids.
