This article defines a property of topological spaces: a property that can be evaluated to true/false for any topological space|View a complete list of properties of topological spaces
This is a variation of normal space. View other variations of normal space
A topological space is termed binormal if its product with the unit interval (with the product topology) is a normal space.
Equivalently (??), a topological space is termed binormal if it is both a normal space and a countably paracompact space.
