Abstract: Let denote the group of homeomorphisms of a metric space onto itself. We say that is conjugate to if for some . In this paper, we study the questions: When is conjugate to which is a uniform homeomorphism or can be extended to a homeomorphism on the metric completion of Typically for a complete metric space , we prove that is conjugate to a uniform homeomorphism if is uniformly approximated by uniform homeomorphisms. In case , we obtain a stronger result showing that every homeomorphism on is, in fact, conjugate to a smooth Lipschitz homeomorphis. For a noncomplete metric space , we provide answers to the existence of under several different settings. Our results are concerned mainly with infinite-dimensional manifolds.
