Tilting complexes and codimension functions over commutative noetherian rings
M Hrbek, T Nakamura, J Šťovíček - arXiv preprint arXiv:2207.01309, 2022 - arxiv.org
In the derived category of a commutative noetherian ring, we explicitly construct a silting
object associated with each sp-filtration of the Zariski spectrum satisfying the" slice" …

Silting, cosilting, and extensions of commutative ring
We study the transfer of (co) silting objects in derived categories of module categories via
the extension functors induced by a morphism of commutative rings. It is proved that the …

Hearts for commutative Noetherian rings: torsion pairs and derived equivalences
S Pavon, J Vitória - Documenta Mathematica, 2021 - dev.ems.press
Over a commutative noetherian ring R, the prime spectrum controls, via the assignment of
support, the structure of both Mod (R) and D (R). We show that, just like in Mod (R), the …
