Endomorphism Algebras Over Commutative Rings and Torsion in Self Tensor Products

Abstract Let R be a commutative Noetherian local ring. We study tensor products involving a finitely generated R -module M through the natural action of its endomorphism ring. In particular, we study torsion properties of self tensor products in the case where $${\text {End}}_R(M...
