Sharp Bounds and Extremal Fuzzy Graphs for the Fuzzy Sombor Index

Jasem Hamoud

The fuzzy Sombor index applies the classical Sombor index to fuzzy graphs, incorporating both edge membership values and fuzzy vertex degrees. For , the general fuzzy Sombor i…

Structural Components Dominate Asymptotic Behavior on Sombor Index with Iterated Pendant Constructions

Jasem Hamoud

The Sombor index, a degree-based topological descriptor introduced by Gutman in 2021, lacks closed-form expressions for complex hierarchical trees with multi-level pendant structur…

Bounds on the Albertson Index for Trees with Given Degree Sequences

Jasem Hamoud, Duaa Abdullah

In this paper, we presents novel and sharp bounds on the Albertson index of trees, revealing deep connections between degree sequences and graph irregularity where the Albertson in…
