In mathematics, a monotonically normal space is a particular kind of normal space, with some special characteristics, and is such that it is hereditarily normal, and any two separated subsets are strongly separated. They are defined in terms of a monotone normality operator. A topological space is said to be ''monotonically normal'' if the following condition holds: For every , where G is open, there is an open set such that # #if then either or . There are some equivalent criteria of monotone normality. ==Equivalent definitions== 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「Monotonically normal space」の詳細全文を読む スポンサード リンク
