A Note on atom bond connectivity index
2012The atom bond connectivity index of a graph is a new topological index was defined by E. Estrada as ABC(G) uvE (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.

On generalized atom-bond connectivity index of cacti
2019Summary: The generalized atom-bond connectivity index of a graph \(G\) is denoted by ABC\(_a(G)\) and defined as the sum of weights \(\left(\frac{d(u)+d(v)-2}{d(u)d(v)}\right)^\alpha\) over all edges \(uv \in G\), where \(d(u)\) is the degree of the vertex \(u\) in \(G\), and \(\alpha\) is an arbitrary non-zero real number. A cactus is a graph in which

Remarks on atom bond connectivity index
2012A topological index is a function Top from Σ into real numbers with this property that Top(G) = Top(H), if G and H are isomorphic. Nowadays, many of topological indices were defined for different purposes. In the present paper we present some properties of atom bond connectivity index.

Atom bond connectivity temperature index of certain nanostructures
2018In the study of QSPR/QSAR, topological indices such as Zagreb index, Randic index, atom-bond connectivity index are exploited to estimate the bioactivity of chemical compounds. Inspired by many degree based topological indices, we propose here a new topological index, called the Atom Bond Connectivity temperature index ABCT(G) of a molecular graph G ...

Extremal Results and Bounds for Atom-Bond Sum-Connectivity Index
Match Communications in Mathematical and in Computer ChemistryThe 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.
