由度量空间诱导的*-拓扑和s-拓扑(* -Topology and s-topology induced by metric space)
This paper studies * -topology and s-topology in polysaturated nonstandard model,which are induced by metric space on two nonstandard sets. In order to construct * -topology , the set of finite points is introduced. It shows that every internal set is compact, every open set is saturated and stand...
