Abstract:For metrically generated constructs X we give an internal characterization of the regular closure operator on X, determined by the subconstruct X 0, consisting of its T 0 objects. This allows us to describe the epimorphisms in X 0 and to show that all the constructs of that type are cowellpowered. We capture many known results but our method also gives solutions in cases where the epimorphism problem was still open.
