Extremal Results and Bounds for Atom-Bond Sum-Connectivity Index [PDF]

Match Communications in Mathematical and in Computer Chemistry
The ABS (atom-bond sum-connectivity) index is a topological index, that was introduced in 2022 by amalgamating the main ideas of two well-examined indices. Mathematical aspects (especially, extremal results and bounds) of the ABS index have already been studied considerably.

Extremal Trees with Respect to the Difference between Atom-Bond Connectivity Index and Randić Index

Symmetry, 2020
Let G be a simple, connected and undirected graph. The atom-bond connectivity index (ABC(G)) and Randić index (R(G)) are the two most well known topological indices. Recently, Ali and Du (2017) introduced the difference between atom-bond connectivity and

On the Maximum Atom-Bond Sum-Connectivity Index of Trees

MATCH – Communications in Mathematical and in Computer Chemistry, 2023
Topological indices have been under study since 1947 when H. Wiener proposed a mathematical formula to order the boiling temperatures of isomers of alkanes. Since then, over 3000 similar mathematical formulae have been defined and studied by mathematicians, chemists and by other scientists.

Atom-Bond Connectivity Index in Various Graphs

ECS Transactions, 2022
A topological index, furthermore identified by way of connective index, is a molecular construction descriptor intended from a molecular graph of a chemical composite, which symbolizes its topology. Different topological indices remain branded established on their degree, spectrum, and distance.

A Note on atom bond connectivity index

2012
The atom bond connectivity index of a graph is a new topological index was defined by E. Estrada as ABC(G)  uvE (dG(u) dG(v) 2) / dG(u)dG(v) , where G d ( u ) denotes degree of vertex u. In this paper we present some bounds of this new topological index.
