Abstract: The goal point of recent attempts to classify indecomposable modules over non-artinian rings has been pullback rings. The purpose of this paper is to outline a new approach to the classification of indecomposable weak comultiplication modules with finite-dimensional top over certain kinds of pullback rings.

Keywords: Pullback, Separated modules and representations, Non-separated modules, Weak comultiplication modules, Dedekind domains, Pure-injective modules, Prüfer modules.
