ABSORBING MULTIPLICATION MODULES OVER PULLBACK RINGS

Abstract

Following some ideas and a technique introduced in [Comm. Algebra 41 (2013), pp. 776-791] we give a complete classification, up to isomorphism, of all indecomposable 2-absorbing multiplication modules with finitedimensional top over pullback of two discrete valuation domains with the same residue field.

Keywords

• Pullback,separated,non-separated,2-absorbing multiplication module
