On the Maximum Atom-Bond Sum-Connectivity Index of Trees
MATCH – Communications in Mathematical and in Computer Chemistry, 2023Topological 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.

Sharp lower bounds on the sum-connectivity index of trees
Discrete Mathematics, Algorithms and Applications, 2021The 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. In this paper, some
