Silting objects

L Angeleri Hügel - Bulletin of the London Mathematical Society, 2019 - Wiley Online Library
We give an overview of recent developments in silting theory. After an introduction on torsion
pairs in triangulated categories, we discuss and compare different notions of silting and …

Lifting and restricting t‐structures

F Marks, A Zvonareva - Bulletin of the London Mathematical …, 2023 - Wiley Online Library
We explore the interplay between t‐structures in the bounded derived category of finitely
presented modules and the unbounded derived category of all modules over a coherent ring …

Parametrizing torsion pairs in derived categories

L Angeleri Hügel, M Hrbek - … Theory of the American Mathematical Society, 2021 - ams.org
We investigate parametrizations of compactly generated t-structures, or more generally, t-
structures with a definable coaisle, in the unbounded derived category $\mathrm …

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 …

Telescope conjecture for homotopically smashing t-structures over commutative noetherian rings

M Hrbek, T Nakamura - Journal of Pure and Applied Algebra, 2021 - Elsevier
We show that any homotopically smashing t-structure in the derived category of a
commutative noetherian ring is compactly generated. This generalizes the validity of the …

Hearts for commutative Noetherian rings: torsion pairs and derived equivalences

S Pavon, J Vitória - Documenta Mathematica, 2021 - content.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 …

Compactly generated tensor t-structures on the derived categories of Noetherian schemes

UV Dubey, G Sahoo - Mathematische Zeitschrift, 2023 - Springer
We introduce a tensor compatibility condition for t-structures. For any Noetherian scheme X,
we prove that there is a one-to-one correspondence between the set of Thomason filtrations …

Singular equivalences to locally coherent hearts of commutative noetherian rings

M Hrbek, S Pavon - Journal of Algebra, 2023 - Elsevier
We show that Krause's recollement exists for any locally coherent Grothendieck category
whose derived category is compactly generated. As a source of such categories, we …

Gluing compactly generated t-structures over stalks of affine schemes

M Hrbek, J Hu, R Zhu - Israel Journal of Mathematics, 2024 - Springer
We show that compactly generated t-structures in the derived category of a commutative ring
R are in a bijection with certain families of compactly generated t-structures over the local …

On the uniqueness of infinity-categorical enhancements of triangulated categories

B Antieau - arXiv preprint arXiv:1812.01526, 2018 - arxiv.org
We study the problem of when triangulated categories admit unique infinity-categorical
enhancements. Our results use Lurie's theory of prestable infinity-categories to give …
