The set ''G'' is open and a topological group. Consider the identity component :''G''0, or in other words the connected component containing the identity 1 of ''A''; ''G''0 is a normal subgroup of ''G''. The quotient group :Λ''A'' = ''G''/''G''0 is the abstract index group of ''A''. Because ''G''0, being the component of an open set, is both open and closed in ''G'', the index group is a discrete group. 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「Abstract index group」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.
