Abstract
Given a Tychonoff space , let be the set of remote points of . We view as a topological space. In this paper we assume that is metrizable and ask for conditions on so that is homeomorphic to . This question has been studied before by R. G. Woods and C. Gates. We give some results of the following type: if has topological property and is homeomorphic to , then also has . We also characterize the remote points of the rationals and irrationals up to some restrictions. Further, we show that and have open dense homeomorphic subspaces if and are both nowhere locally compact, completely metrizable and share the same cellular type, a cardinal invariant we define.
