Abstract: We prove that the epimorphic image of a Dedekind domain A is characterized (up to A-isomorphisms) by its torsion submodule (as an A-module) and the torsion-free quotient by its torsion submodule. Necessary and sufficient conditions are given on a torsion and torsion-free A-module in order that they be the corresponding parts of an epimorphic image of A.
