摘要 利用度序列的优超偏序关系,分别刻画了给定匹配数或独立数的具有最小和次小Wiener指数的n阶极值树特征。 In this pa per,by using the majorization partial ordering of degree sequences,the author characterized the extremal trees with the minimum and the second minimum Wiener indices among all the nvertex trees with given matching number or independent number respectively.
