Hosoya Polynomials Of Some Semiconducotors
Journal of Kufa for Mathematics and Computer, 2014 The Hosoya polynomial of a graph G is a graphical invariant polynomial that its first derivative at x = 1 is equal to the Wiener index and second derivative at x =1 is equal to the hyperï€Wiener index.

Hosoya polynomial of the subdivided join [PDF]
Kuwait Journal of Science, 2019 The Hosoya polynomials of diameter 1 and diameter 2 graphs are known. We extend the concept of a vertex join of a graph to q-vertex join. Then we give the formula of the Hosoya polynomial of a $q$-vertex join of a complete graph and the formula of the ...

Hosoya polynomial of composite graphs [PDF]
Discrete Mathematics, 2001 Let G1+G2, G1∇G2, G1[G2], G1∘G2 and G1{G2} be the sum, join, composition, corona and cluster, respectively, of the graphs G1 and G2. Elsewhere, Yeh and Gutman computed the Wiener number of these composite graphs.

A method for computing the edge-Hosoya polynomial with application to phenylenes [PDF]
match Communications in Mathematical and in Computer Chemistry, 2023 The edge-Hosoya polynomial of a graph is the edge version of the famous Hosoya polynomial. Therefore, the edge-Hosoya polynomial counts the number of (unordered) pairs of edges at distance $k ge 0$ in a given graph. It is well known that this polynomial
