结果表明,相同维度 d ≥ 2 的两个可定向可数黎曼流形的 1 < p < d 的 Royden p 紧致化是同胚的,当且仅当这两个黎曼流形之间存在同胚,并且在它们的一些紧子集之外是准等距的。
It is shown that Royden p -compactifications for 1 < p < d of two orientable and countable Riemannian manifolds of the same dimension d ≥ 2 are homeomorphic if and only if there exists a homeomorphism between these two Riemannian manifolds which is quasi-isometric outside some of their compact subsets.
