Sombor index – one year later [PDF]
, 2020 The Sombor index (SO) is a vertex–degree–based graph invariant, invented in the Summer of 2020, and made publicly available in early 2021. In less than one year, a remarkable number (almost fifty) research papers on this topological index were produced.

Extremal trees, unicyclic and bicyclic graphs with respect to $p$-Sombor spectral radii
, 2023 For a graph $G=(V,E)$ and $v_{i}\in V$, denote by $d_{v_{i}}$ (or $d_{i}$ for short) the degree of vertex $v_{i}$. The $p$-Sombor matrix $\textbf{S}_{\textbf{p}}(G)$ ($p\neq0$) of a graph $G$ is a square matrix, where the $(i,j)$-entry is equal to ...

Implementation of multi-criteria decision making for the ranking of drugs used to treat bone-cancer [PDF]
The concept of "topological index" refers to a numerical value determined by the structure of a chemical network. It serves to determine the physicochemical and biological properties of diverse medications, offering a more precise depiction of the ...

Maximum values of the Sombor-index-like graph invariants of trees and connected graphs
A set of novel vertex-degree-based invariants was introduced by Gutman, denoted by \newline $SO_1, SO_2, \ldots,SO_6$. These invariants were constructed through geometric reasoning based on a new graph invariant framework.
