Auslander-type conditions and cotorsion theory
Auslander-type conditions cotorsion theory functorially finite

We study the properties of rings satisfying Auslander-type conditions. If an artin algebra A satisfies the Auslander condition (that is, A is an ∞-Gorenstein artin algebra), then we construct two kind...

We give a criterion for the sheaf of Kähler differentials on a cone over a smooth projective variety to be torsionfree.
