A topological space is called epi--normal (epi--normal) if there is a coarser topology on such that is -normal (-normal). We investigate these properties and show some examples to explain the relationships of epi--normal (epi--normal) with other weaker versions of normality and some topological spaces.

Epi--Normality 和 Epi--Normalality

拓扑空间 被称为外延- -正态（epi- -正态）如果有一个更粗的拓扑，使得是-正常（-正常）。我们研究了这些属性并展示了一些例子来解释外向- -正态（外向- -正态）与其他较弱版本的正态和一些拓扑空间的关系。
