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