| Dec 30, 2011 at 8:54 | comment | added | Ryan Budney | Yes, there is such an object. The idea for the definition comes from the universal mapping property encoded in the definition of adjoint. I'd call this functor the "maximal Hausdorff quotient" of a space. This is a good homework problem in a point-set topology course. Given a topological space $X$, consider all equivalence relations on $X$ with Hausdorff quotient, and take the intersection of all such equivalence relations. | |
