摘要
本文研究做为最古老的基于距离的拓朴指标之一—Wiener指标.对于Tadpole图Tn,k,循环图Cn,轮式图Wn+1和Helm图Hn+1,文中分别导出了它们的细分图的Wiener多项式的表达式.
One of the oldest distance-based topological index,the Wiener index is studied,and expressions for the Wiener polynomial of the subdivision graph of the Tadpole graph Tn,k,the cycle Cn,the wheel graph Wn+1 and the Helm graph Hn+1 are presented in this paper.
