Weak comultiplication modules over a pullback of commutative local Dedekind domains

Reza Ebrahimi Atani, Shahabaddin Ebrahimi Atani

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.
