Nima Ghanbari, Mohammad Ali Dehghanizadeh, Saeid Alikhani

Published Online: 02 Mar 2026DOI: 10.47974/JIOS-1845

In this paper: The overall variation in vertex connections within a graph, known as the total irregularity, is quantified by summing half the absolute differences between the degrees of every vertex pair. This study...

Sombor polynomial (function) of a graph

Nima Ghanbari, Saeid Alikhani

Published Online: 01 May 2024DOI: 10.47974/JDMSC-1623

In this paper: Let G = (V, E)  be a finite simple graph. The Sombor index SO(G) of G is defined as ΣuvϵE(G) √d2u+d2v, where du is the degree of vertex u in G. We consider the Sombor polynomial (function) as  S(G, x)...
