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" …

Tilting, cotilting, and spectra of commutative noetherian rings

L Angeleri Hügel, D Pospisil, J Stovicek… - arXiv e …, 2012 - ui.adsabs.harvard.edu
We classify all tilting and cotilting classes over commutative noetherian rings in terms of
descending sequences of specialization closed subsets of the Zariski spectrum …

[HTML][HTML] Colocalization and cotilting for commutative noetherian rings

J Trlifaj, S Şahinkaya - Journal of Algebra, 2014 - Elsevier
For a commutative noetherian ring R, we investigate relations between tilting and cotilting
modules in Mod–R and Mod–R m, where m runs over the maximal spectrum of R. For each …

Minimal silting modules and ring extensions

LA Hügel, W Cao - Science China Mathematics, 2022 - Springer
Ring epimorphisms often induce silting modules and cosilting modules, termed minimal
silting or minimal cosilting. The aim of this paper is twofold. Firstly, we determine the minimal …

Tilting classes over commutative rings

M Hrbek, J Šťovíček - Forum Mathematicum, 2020 - degruyter.com
We classify all tilting classes over an arbitrary commutative ring via certain sequences of
Thomason subsets of the spectrum, generalizing the classification for noetherian …

Silting, cosilting, and extensions of commutative ring

S Breaz, M Hrbek, GC Modoi - arXiv preprint arXiv:2204.01374, 2022 - arxiv.org
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 …

Compactly generated t-structures in the derived category of a commutative ring

M Hrbek - Mathematische Zeitschrift, 2020 - Springer
We classify all compactly generated t-structures in the unbounded derived category of an
arbitrary commutative ring, generalizing the result of Alonso Tarrío et al.(J Algebra 324 (3) …

Rigidification of connective comodules

M Péroux - arXiv preprint arXiv:2006.09398, 2020 - arxiv.org
Let $\mathbb {k} $ be a commutative ring with global dimension zero. We show that we can
rigidify homotopy coherent comodules in connective modules over the Eilenberg-Mac Lane …

Perfect even modules and the even filtration

P Pstrągowski - arXiv preprint arXiv:2304.04685, 2023 - arxiv.org
Inspired by the work of Hahn-Raksit-Wilson, we introduce a variant of the even filtration
which is naturally defined on $\mathbf {E} _ {1} $-rings and their modules. We show that our …
