On the Difference of Atom-Bond Sum-Connectivity and Atom-Bond-Connectivity Indices

Akbar Ali, Ivan Gutman, Izudin Redzepovic +3

The atom-bond-connectivity (ABC) index is one of the well-investigated degree-based topological indices. The atom-bond sum-connectivity (ABS) index is a modified version of the ABC…

Harmonic-Arithmetic Index of (Molecular) Trees

Abeer M. Albalahi, Akbar Ali, Abdulaziz M. Alanazi +2

Let $G$ be a graph. Denote by $d_{x}$ , $E (G)$ , and $D (G)$ the degree of a vertex $x$ in $G$ , the set of edges of $G$ , and the degree set of $G$ , respectively. This paper proposes to…

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

Tariq Alraqad, Hisham Saber, Akbar Ali +1

The atom-bond sum-connectivity (ABS) index of a graph $G$ with edges $e_{1}, \dots, e_{m}$ is the sum of the numbers $1 - 2 (d_{e_{i}} + 2)^{- 1}$ over $1 \leq i \leq m$ , where $d_{e_{i}}$ is…
