Extremum sum-connectivity index of trees and unicyclic graphs

Asian-European Journal of Mathematics, 2022
The sum-connectivity index of a graph [Formula: see text] is defined as the sum of weights [Formula: see text] over all edges [Formula: see text] of [Formula: see text], where [Formula: see text] and [Formula: see text] are the degrees of the vertices [Formula: see text] and [Formula: see text] in [Formula: see text], respectively.

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.
