Tilting via torsion pairs and almost hereditary noetherian rings

Rings and Algebras 2011-05-23 v2 Representation Theory

Abstract

We generalize the tilting process by Happel, Reiten and Smal{\o} to the setting of finitely presented modules over right coherent rings. Moreover, we extend the characterization of quasi-tilted artin algebras as the almost hereditary ones to all right noetherian rings.
