AB5*-modules with the exchange property

Yasser Ibrahim, Mohamed Yousif

Research output: Contribution to journalJournal articlepeer-review


We prove that every (Formula presented.) -module has an indecomposable decomposition. As an immediate consequence, every (Formula presented.) -module M with the finite exchange is clean and has the full exchange. Moreover, in this case the module M admits an indecomposable decomposition (Formula presented.) with each Mi having local endomorphism ring, and the decomposition complements direct summands.
