*Definition [#w2753743]
-A topological space (X,τ) is said to be strong T_0 if for each point x of X, the [[derived set]] {x}' is a finite union of a family of closed sets such that the intersection of non-empty members of the family is empty and at least one of t
*Property [#n35e20f2]
-A [[normal]] strong T_0 ⇒ [[T_4]]
*Reference [#rb32d3ce]
