A [[topological space]] X is completely regular if singleton sets are closed in X and any point x in X and any closed subset B of X not containing x can be seperated by a continuous function.
A [[topological space]] X is completely regular if singleton sets are closed in X and any point x in X and any closed subset B of X not containing x can be seperated by a [[continuous function]].
The subspace of a completely regular space is a completely regular space; the product of 2 completely regular spaces is a completely regular space.
