Bounded distortion homeomorphisms on ultrametric spaces
Bruce Hughes, Álvaro Martínez-Pérez, Manuel A. Morón
It is well-known that quasi-isometries between R-trees induce power quasi-symmetric homeomorphisms between their ultrametric end spaces. This paper investigates power quasi-symmetr…

A metric between quasi-isometric trees
Álvaro Martínez-Pérez
It is known that PQ-symmetric maps on the boundary characterize the quasi-isometry type of visual hyperbolic spaces, in particular, of geodesically complete \br-trees. We define a…
