摘要
在田丰教授等对树的拉普拉斯谱半径排序以及袁西英等对完美匹配树的拉普拉斯谱半径排序研究的基础上,对完美匹配树的谱半径进行了进一步的研究.对一些分类作了内部排序,增加了若干分类并作了讨论.最后得出了第七和第八大谱半径并给出了相应的完美匹配树.
Based on the former research of the order of trees and trees with perfect matching by professors Tian Feng and Yuan Xiying. A further research is presented in this paper. The seventh and the eighth largest Laplacian radii of the trees with perfect matching are determined and along with the graphs respectively.
