Hearts for commutative noetherian rings: torsion pairs and derived equivalences

Abstract

Over a commutative noetherian ring RR, the prime spectrum controls, via the assignment of support, the structure of both Mod(R)\mathsf{Mod}(R) and D(R)\mathsf{D}(R). We show that, just like in Mod(R)\mathsf{Mod}(R), the assignment of support classifies hereditary torsion pairs in the heart of any nondegenerate compactly generated tt-structure of D(R)\mathsf{D}(R). Moreover, we investigate whether these tt-structures induce derived equivalences, obtaining a new source of Grothendieck categories which are derived equivalent to Mod(R)\mathsf{Mod}(R).
