Euler-Sombor index of chemical graphs and its applications

Fateme Movahedi, A. Karimi, Z. Samiei

Published Online: 13 Dec 2025DOI: 10.47974/JIOS-1975

In this paper: Given a simple graph π’œ = (Vπ’œ, Eπ’œ). The Euler-Sombor index of π’œ is given byΒ  EU(π’œ) = Stk∈Eπ’œ √h(t)2 + h(k)2 + h(t)h(k), in which Ξ·(c) is the degree of c ∈ Vπ’œ. In this paper, we focus on the chemical gra...

Computing new degree-based topological indices associated with the zero-divisor graphs of finite commutative rings

A. Karimi, Fateme Movahedi, S. M. Taheri

Published Online: 28 Jul 2025DOI: 10.47974/JDMSC-1864

In this paper: Consider a commutative ring β„œ. Let ℨ*(β„œ) denote the set of zero-divisors of β„œ\{0}. A zero-division graph, denoted by Ξ“(β„œ), is a graph interrelated with the ring β„œ, where the vertex set consists of the...
