On the Wiener Complexity and the Wiener Index of Fullerene Graphs [PDF]

open access: yesMathematics, 2019
Fullerenes are molecules that can be presented in the form of cage-like polyhedra, consisting only of carbon atoms. Fullerene graphs are mathematical models of fullerene molecules.

On Wiener Polarity Index and Wiener Index of Certain Triangular Networks

open access: yesJournal of Chemistry, 2021
A topological index of graph G is a numerical quantity which describes its topology. If it is applied to the molecular structure of chemical compounds, it reflects the theoretical properties of the chemical compounds. A number of topological indices have

Wiener index for an intuitionistic fuzzy graph and its application in water pipeline network

open access: yesAin Shams Engineering Journal, 2023
The usefulness of different topological indices is inevitable in various fields such as Chemistry, Electronics, Economics and Business studies, medical and social sciences. The “purpose of this paper is to study” Wiener index for the Intuitionistic fuzzy

The Wiener index, degree distance index and Gutman index of composite hypergraphs and sunflower hypergraphs. [PDF]

open access: yesHeliyon, 2022
Topological invariants are numerical parameters of graphs or hypergraphs that indicate its topology and are known as graph or hypergraph invariants. In this paper, topological indices of hypergraphs such as Wiener index, degree distance index and Gutman ...

Generalizations of Wiener Polarity Index and Terminal Wiener Index [PDF]

open access: yesGraphs and Combinatorics, 2012
In theoretical chemistry, distance-based molecular structure descriptors are used for modeling physical, pharmacologic, biological and other properties of chemical compounds. We introduce a generalized Wiener polarity index $W_k (G)$ as the number of unordered pairs of vertices ${u, v}$ of $G$ such that the shortest distance $d (u, v)$ between $u$ and $

The Wiener index of signed graphs [PDF]

open access: yesApplied Mathematics and Computation, 2021
The Wiener index of a graph W (G) is a well studied topological index for graphs. An outstanding problem of Šoltés is to find graphs G such that W (G) = W (G − v) for all vertices v ∈ V (G), with the only known example being G = C11.

Wiener index of quadrangulation graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2020
The Wiener index of a graph $G$, denoted $W(G)$, is the sum of the distances between all pairs of vertices in $G$. E. Czabarka, et al. conjectured that for an $n$-vertex, $n\geq 4$, simple quadrangulation graph $G$, \begin{equation*}W(G)\leq \begin ...

Upgrading the Wiener index [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
The Wiener index Wis the oldest molecular-graph-based structure-descriptor. It is defined as the sum of the distances of all pairs of vertices of the molecular graph G, where the distance is the number of edges in the shortest path connecting the ...

Wiener Index and Remoteness in Triangulations and Quadrangulations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2019
Let $G$ be a a connected graph. The Wiener index of a connected graph is the sum of the distances between all unordered pairs of vertices. We provide asymptotic formulae for the maximum Wiener index of simple triangulations and quadrangulations with ...
