设G是一个具有顶点集V(G)的化学图,图G中的顶点u到v之间的距离为:图G的变量x中的Hosoya多项式为.本文给出了一个计算一五方碳纳米锥的Hosoya多项式的解析表达式。此外,还可以很容易地获得一系列基于距离的分子结构描述符,如著名的Wiener指数、超Wiener指数和Harary指数。从这个角度出发,我们推广了Ashrafi和Mohammad-Abadi(4)关于一五方碳纳米锥的Wiener指数的结果。
Let G be a chemical graph with vertex set V(G) and the distance between vertices u and v in G. The Hosoya polynomial in variable x of graph G is . In this article, we give an analytical expression for calculating the Hosoya polynomial of one-pentagonal carbon nanocone. Furthermore, a series of distance-based molecular structure descriptors, such as the well-known Wiener index, the hyper-Wiener index, and the Harary index, can be easily obtained. From this point of view, we generalize the results on the Wiener index of one-pentagonal carbon nanocone by Ashrafi and Mohammad-Abadi (4).
