Isomorphism Of Trees And Isometry Of Ultrametric Spaces, Oleksiy Dovgoshey
Theory and Applications of Graphs
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.
