Abstract :The purpose of this paper is to introduce the concept of 2-absorbing comultiplication modules, which form a subclass of the class of pure-injective modules over pullback rings. A full description of all indecomposable 2- absorbing comultiplication modules with nite-dimensional top over the pull- back of two discrete valuation domains with the same residue eld is given.
Keywords : Pullback, separated, non separated, 2 absorbing comultiplication module
