Degree-based topological indices of the idempotent graph of the ring Zn

Examples and Counterexamples
Let R be a finite commutative ring with a non-zero identity, and Id(R) be the set of idempotent elements of R. The idempotent graph of R, denoted by GId(R), is a simple undirected graph with all elements of R as vertices, and two distinct vertices u, v ...

On Sombor Indices of Some Structural Isomers

International Research Journal on Advanced Science Hub
Some degree based topological indices can be used to predict chemical properties of molecular structures. Sombor index, reduced Sombor index and average Sombor index on chemical trees of some structural isomers are calculated. In particular Carbon structures of alcohol family with OH in 1st, 2nd, 3rd ….

Status Elliptic Sombor and Modified Status Elliptic Sombor Indices of Graphs

Journal of Mathematics and Informatics
In this study, we introduce the status elliptic Sombor and modified status elliptic Sombor indices and their corresponding exponentials of a graph. Furthermore, we compute these indices for wheel graphs and friendship graphs.

Status Sombor Indices of Unitary Cayley Graph

Indian Journal Of Science And Technology
Objectives: The objective of the study is to obtain the values of status Sombor indices for the unitary Cayley graph. Methods: The unitary Cayley graph 𝑋𝑛 has vertex set 𝑍𝑛 = {0, 1, 2, ...𝑛 − 1}. Vertices a, and b are adjacent, if 𝑔𝑐𝑑(𝑎 − 𝑏, 𝑛) = 1. The status 𝜎 (𝑢) of a vertex u in a graph, G is the sum of distances of all other vertices from u in 𝐺 ...

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.

Temperature-based Evapotranspiration in the WSVI Drought Index Implementation: Case Study: Pannonian Basin [PDF]

Drought is a natural hazard that affects environmental and socio-economic development. In this study, the Water Surplus Variability Index (WSVI), which is based on both precipitation and Penman-Monteith (PM) evapotranspiration (ET) estimates, was used to

NEW VERTEX-EDGE SOMBOR, NIRMALA AND MISBALANCE INDICES

The molecular structure of a compound contains all the information which would help to determine its chemical, biological, and physical properties. With the help of a theoretical descriptor tool known as topological indices, one can assess these properties. In this paper, we define new vertex-edge degree topological indices namely, the ve-degree Sombor
