On a Conjecture Concerning the Complementary Second Zagreb Index

Hicham Saber, Tariq Alraqad, Akbar Ali +2

The complementary second Zagreb index of a graph $G$ is defined as $c M_{2} (G) = \sum_{uv \in E (G)} ∣ (d_{u} (G))^{2} - (d_{v} (G))^{2} ∣$ , where $d_{u} (G)$ denotes the degree of a vertex $u$ in $G$ and…

Minimum Atom-Bond Sum-Connectivity Index of Trees With a Fixed Order and/or Number of Pendent Vertices

Tariq A. Alraqad, Igor Z. Milovanovic, Hicham Saber +3

Let $d_{u}$ be the degree of a vertex $u$ of a graph $G$ . The atom-bond sum-connectivity (ABS) index of a graph $G$ is the sum of the numbers $(1 - 2 (d_{v} + d_{w})^{- 1})^{1/2}$ over all edg…
