Further results on the lower bound on reduced Zagreb index of trees

Milan BaÅ¡iÄ, Aleksandar IliÄ

For a graph $G$ , the general reduced second Zagreb index is defined as $GR M_{I^} » (G) = uv \in E \sum (d e g (u) + I^») (d e g (v) + I^»),$ where $I^»$ is an arbitrary real number and $deg…

Trees with maximum $I ¨ $ -irregularity under a prescribed maximum degree 6

Milan BaÅ¡iÄ

The sigma-irregularity index $I ¨ (G) = \sum_{uv \in E (G)} (d_{G} (u) - d_{G} (v))^{2}$ measures the total degree imbalance along the edges of a graph. We study extremal problems for $I ¨ (T)$ …

Maximum values of the Sombor-index-like graph invariants of trees and connected graphs

Milan BaÅ¡iÄ

A set of novel vertex-degree-based invariants was introduced by Gutman, denoted by \newline $S O_{1}, S O_{2}, \dots, S O_{6}$ . These invariants were constructed through geometric reasoning…
