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.

Famous quotes containing the words normal and/or space:
“Freedom is poetry, taking liberties with words, breaking the rules of normal speech, violating common sense. Freedom is violence.”
—Norman O. Brown (b. 1913)
“Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.”
—Alicia F. Lieberman (20th century)
