Generalized trace submodules and centers of endomorphism rings
Justin Lyle
Let be a commutative Noetherian local ring and a finitely generated -module. We introduce a general form of the classically studied trace map that unifies several notion…

Endomorphism algebras over commutative rings and torsion in self tensor products
Justin Lyle
Let be a commutative Noetherian local ring. We study tensor products involving a finitely generated -module through the natural action of its endomorphism ring. In parti…
