forgetful functor from Hausdorff spaces to topological spaces
- Notation:
- Domain: category of Hausdorff spaces
- Codomain: category of topological spaces

This is the inclusion functor that maps a Hausdorff space to itself. It can also be viewed as a forgetful functor, since Hausdorff spaces "forget" that they are Hausdorff.
