Continuous function compact space and its codomain is Hausdorff, then it is a homeomorphism. Given a function where "X" is a topological space and "S" is a set (without a specified topology), the final topology on "S" is defined by letting the open sets of "S" be those subsets "A" of "S" for which "f"("A") is open in "X". If "S" has an existing topology, "f" is continuous with respect to this topology if and only if the existing topology is coarser than the final topology on "S". Thus the final topology can be characterized as the finest topology on "S" that
