Hosoya Polynomial for Subdivided Caterpillar Graphs
Combinatorial Chemistry & High Throughput Screening, 2022Background: Computing Hosoya polynomial for the graph associated with the chemical compound plays a vital role in the field of chemistry. From Hosoya polynomial, it is easy to compute Weiner index(Weiner number) and Hyper Weiner index of the underlying molecular structure.

Hosoya polynomials and corresponding indices of aramids
International Journal of Geometric Methods in Modern Physics, 2023Aramids are man-made high performance fibers admitting useful industrial applications. Aramids can be classified into para-aramids and meta-aramids. Kevlar is a para-aramid and Nomex is a meta-aramid. This work is devoted to compute the empirical formula for the Hosoya polynomial of these aramids.

The Edge-Hosoya Polynomial of Catacondensed Benzenoid Graphs Associated with its Hosoya Polynomial
Match Communications in Mathematical and in Computer ChemistryThis paper reveals the relationship between edge-Hosoya polynomial and the Hosoya polynomial of catacondensed benzenoid graphs. The result shows that, for a catacondensed benzenoid graph, the computations of the edge-Hosoya polynomial can be reduced to that of the Hosoya polynomial.

Reliability Hosoya-Wiener Polynomial of Double Weighted Trees
Fundamenta Informaticae, 2016Reliability Hosoya-Wiener polynomial for edge weighted graphs is defined, that can be used as a measure of reliability of a communication network. Each edge is assigned two weights, reliability and communication delay. Some basic properties are given and a recursive formula for the reliability Hosoya-Wiener polynomial of a rooted tree is proved that ...

Hosoya polynomials of TUC4C8(S) nanotubes
Journal of Mathematical Chemistry, 2008The Hosoya polynomial of a chemical graph G is \({H(G,x)=\sum\nolimits_{\{u, v\}\subseteq V(G)} x^{d_G(u, v)}}\) , where dG(u, v) denotes the distance between vertices u and v. In this paper, we obtain analytical expressions for Hosoya polynomials of TUC4C8(S) nanotubes. Accordingly, the Wiener index, obtained by Diudea et al. (MATCH Commun.

The polygonal cylinder and its Hosoya polynomial
Online Journal of Analytic Combinatorics, 2020We introduce a polygonal cylinder \( C_{m,n} \), using the Cartesian product of paths \( P_m \) and \( P_n \) and using topological identification of vertices and edges of two opposite sides of \( P_m \times P_n \), and give its Hosoya polynomial, which, depending on odd and even \( m \), is covered in seven separate cases.

On the roots of Hosoya polynomial
Journal of Discrete Mathematical Sciences and Cryptography, 2016AbstractLet G=(V, E) be a simple and a connected graph of diameter D. The Hosoya polynomial of G. is , where d(G, k)≥1, is the number of vertex pairs at distance k. The Wiener index of G is the first derivative of the Hosoya polynomial H(G, x) at x = 1. In this paper, we study the Hosoya polynomial and Wiener index of some family of graphs.
