我们将所有负弯曲的R ~ n或R分类为拟等距。我们证明了这类流形之间的所有拟等距(除了当它们是真实的双曲空间的biLipschitz时)几乎是相似的。通过研究理想边界上的拟对称映射,我们证明了这些结果。
We classify all negatively curved R n oR up to quasiisometry. We show that all quasiisometries between such manifolds (except when they are biLipschitz to the real hyperbolic spaces) are almost similarities. We prove these results by studying the quasisymmetric maps on the ideal boundary of these manifolds.
