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

Milan Bašić, Aleksandar Ilić

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

Trees with maximum $σ$ -irregularity under a prescribed maximum degree 6

Milan Bašić

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

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

Milan Bašić

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…
