On Topological Indices and Their Reciprocals

open access: yesMatch Communications in Mathematical and in Computer Chemistry, 2023
Summary: If \(TI(G)=\sum\limits_\gamma F(\gamma)\) is a topological index of the graph \(G \), then \(RTI(G)=\sum\limits_\gamma \frac{1}{F(\gamma)}\) is the respective reciprocal index. In contemporary mathematical chemistry, a large number of pairs \((TI,RTI)\) have been separately introduced and studied, but their mutual relations eluded attention ...

Topological Descriptors and Polynomials for Analysing the Structure of Antimony Telluride

open access: yesJournal of Mathematics, 2022
In a molecular network, molecules are correlated with numerical values, which are referred to as topological indices. The chemical and physical properties of chemical substances can be determined using topological indices.

Affine Graphs and their Topological Indices [PDF]

open access: yesJournal of Mathematics, 2021
Graphs are essential tools to illustrate relationships in given datasets visually. Therefore, generating graphs from another concept is very useful to understand it comprehensively. This paper will introduce a new yet simple method to obtain a graph from any finite affine plane.

M-Polynomials and Degree-Based Topological Indices of the Molecule Copper(I) Oxide

open access: yesJournal of Chemistry, 2021
Topological indices are numerical parameters used to study the physical and chemical residences of compounds. Degree-based topological indices have been studied extensively and can be correlated with many properties of the understudy compounds.

Machine‐Learning Spectral Indicators of Topology [PDF]

open access: yesAdvanced Materials, 2022
AbstractTopological materials discovery has emerged as an important frontier in condensed matter physics. While theoretical classification frameworks have been used to identify thousands of candidate topological materials, experimental determination of materials’ topology often poses significant technical challenges. X‐ray absorption spectroscopy (XAS)

QSPR Modeling of Fungicides Using Topological Descriptors

open access: yesInternational Journal of Analytical Chemistry, 2023
A topological index is a real number that is obtained from a chemical graph’s structure. Determining the physiochemical and biological characteristics of a variety of medications is useful since it more accurately represents the theoretical ...

Eccentricity-Based Topological Invariants of Dominating David-Derived Networks

open access: yesJournal of Chemistry, 2021
A topological index is a numerical descriptor of the molecular structure based on certain topological features of the corresponding molecular graph. Topological indices are scientific contemplations of a graph that outline its subatomic topology and are ...
