Bing, characterizes when a topological space is metrizable. ==Formal statement== The theorem states that a topological space $X$ is metrizable if and only if it is regular and T0 and has a σ-discrete basis. A family of sets is called σ-discrete when it is a union of countably many discrete collections, where a family $F$ of subsets of a space $X$ is called discrete, when every point of $X$ has a neighborhood that intersects at most one member of $F$. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bing metrization theorem」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
