视双曲空间之间的拟等距

Quasi-isometries between visual hyperbolic spaces

Álvaro Martínez-Pérez

摘要:

证明了两个完全度量空间之间的PQ-对称同胚可以推广到它们的双曲逼近之间的拟等距。利用这个结果证明了两个可视Gromov双曲空间是拟等距的当且仅当它们的边界之间存在PQ-对称同胚。

英文摘要:

We prove that a PQ-symmetric homeomorphism between two complete metric spaces can be extended to a quasi-isometry between their hyperbolic approximations. This result is used to prove that two visual Gromov hyperbolic spaces are quasi-isometric if and only if there is a PQ-symmetric homeomorphism between their boundaries.
