Tilting and silting theory of noetherian algebras

Abstract

We develop silting theory of a noetherian algebra Λ\Lambda over a commutative noetherian ring RR. We study mutation theory of 22-term silting complexes of Λ\Lambda, and as a consequence, we see that mutation exists. As in the case of finite dimensional algebras, functorially finite torsion classes of Λ\Lambda bijectively correspond to silting Λ\Lambda-modules, if RR is complete local. We show a reduction theorem of 22-term silting complexes of Λ\Lambda, and by using this theorem, we study torsion classes of the module category of Λ\Lambda. When RR has Krull dimension one, we describe the set of torsion classes of Λ\Lambda explicitly by using the set of torsion classes of finite dimensional algebras.
