树的同构与超度量空间的isometry

Isomorphism of trees and isometry of ultrametric spaces

Oleksiy Dovgoshey

摘要:

本文研究了有限树的边权生成度量的空间的等距等价于这些树的同构的条件。对树的顶点上的标号生成的超度量空间研究了类似的问题。所得结果概括了一些事实以前已知的系统发育树和Gurvich-Vyalyi单调树。

英文摘要:

We study the conditions under which the isometry of spaces with metrics generated by weights given on the edges of finite trees is equivalent to the isomorphism of these trees. Similar questions are studied for ultrametric spaces generated by labelings given on the vertices of trees. The obtained results generalized some facts previously known for phylogenetic trees and for Gurvich-Vyalyi monotone trees.
