给定度序列树的Wiener指标的极值

The extremal values of the Wiener index of a tree with given degree sequence

Hua Wang

摘要:

图的Wiener指数是所有顶点对之间的距离之和,它是将化学化合物的分子图与实验收集的关于化合物特性的数据相关联的主要描述符之一。研究了在给定的最大度的树中使Wiener指标最小的树。我们的特点,实现最大和最小维纳指数的树,给定的顶点数和度序列。

英文摘要:

The Wiener index of a graph is the sum of the distances between all pairs of vertices, it has been one of the main descriptors that correlate achemical compound's molecular graph with experimentally gathered data regarding the compound's characteristics. The tree that minimizes the Wiener index among trees of given maximal degree was studied. We characterize trees that achieve the maximum and minimum Wiener index, given the number of vertices and the degree sequence.
