Proof of a conjecture on the Wiener index of Eulerian graphs [PDF]
Discrete Applied Mathematics, 2021 The Wiener index of a connected graph is the sum of the distances between all unordered pairs of vertices. A connected graph is Eulerian if its vertex degrees are all even.

Remarks on Wiener Index of Bipolar Fuzzy Incidence Graphs
Frontiers in Physics, 2021 Fuzzy data plays an important role in daily life, and fuzzy structured data is usually represented by fuzzy graphs, where the graph structure is used to describe the associated structure of the fuzzy data.

, 2021 After several years of steady decline, carbon emissions began to rise in 2017. If this trend is not curbed as soon as possible, the efforts made for carbon emission reduction will be wasted.

The Mostar and Wiener index of Alternate Lucas Cubes [PDF]
Transactions on Combinatorics, 2023 The Wiener index and the Mostar index quantify two distance related properties of connected graphs: the Wiener index is the sum of the distances over all pairs of vertices and the Mostar index is a measure of how far the graph is from being distance ...

Algorithms for Computing Wiener Indices of Acyclic and Unicyclic Graphs
Complexity, 2021 Let G=VG,EG be a molecular graph, where VG and EG are the sets of vertices (atoms) and edges (bonds). A topological index of a molecular graph is a numerical quantity which helps to predict the chemical/physical properties of the molecules.

Distance-Based Polynomials and Topological Indices for Hierarchical Hypercube Networks
Journal of Mathematics, 2021 Topological indices are the numbers associated with the graphs of chemical compounds/networks that help us to understand their properties. The aim of this paper is to compute topological indices for the hierarchical hypercube networks. We computed Hosoya

Multicenter Wiener indices and their applications [PDF]
Journal of the Serbian Chemical Society, 2015 The Wiener index W can be viewed as a molecular structure descriptor composed of increments representing interactions between pairs of atoms. A generalization of the W are the Steiner-Wiener indices kW, k=3,4,....

On the Wiener Polynomials of Some Trees [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2007 The Wiener index is a graphical invariant which has found many applications in chemistry. The Wiener Polynomial of a connected graph G is the generating function of the sequence (C(G,k)) whose derivative at x=1 is the Wiener index W(G) of G, in which C(G,
