我们对所有负曲线$R^n进行分类 乘以R$,直到准等距。我们证明了这种流形之间的所有拟等距(除非它们是实双曲空间的双Lipschitz)几乎是相似的。我们通过研究这些流形理想边界上的拟对称映射证明了这些结果。
We classify all negatively curved $R^n times R$ 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.
