Regular subcategories in bounded derived categories of affine schemes

A Elagin, V Lunts - arXiv preprint arXiv:1711.01492, 2017 - arxiv.org
Let $ R $ be a commutative Noetherian ring such that $ X= Spec R $ is connected. We prove
that the category $ D^ b (coh X) $ contains no proper full triangulated subcategories which …

When are KE-closed subcategories torsion-free classes?

T Kobayashi, S Saito - Mathematische Zeitschrift, 2024 - Springer
Let R be a commutative noetherian ring and denote by\({{\,\mathrm {\textsf {mod}}\,}} R\) the
category of finitely generated R-modules. In this paper, we study KE-closed subcategories …

On locally coherent hearts

M Saorín - Pacific Journal of Mathematics, 2017 - msp.org
Let G be a locally coherent Grothendieck category. We show that, under particular
conditions, if a t-structure τ in the unbounded derived category D (G) restricts to the bounded …

Invariants of t-structures and classification of nullity classes

D Stanley - arXiv preprint math/0602252, 2006 - arxiv.org
We construct an invariant of t-structures on the derived category of a Noetherian ring. This
invariant is complete when restricting to the category of quasi-coherent complexes, and also …

On compactly generated torsion pairs and the classification of co-𝑡-structures for commutative noetherian rings

J Šťovíček, D Pospíšil - Transactions of the American Mathematical Society, 2016 - ams.org
We classify compactly generated co-$ t $-structures on the derived category of a
commutative noetherian ring. In order to accomplish this, we develop a theory for compactly …

Bounded t-structures on the category of perfect complexes over a Noetherian ring of finite Krull dimension

H Smith - Advances in Mathematics, 2022 - Elsevier
We classify bounded t-structures on the category of perfect complexes over a commutative,
Noetherian ring of finite Krull dimension, extending a result of Alonso Tarrío, Jeremías López …

Faltings' annihilator theorem and t-structures of derived categories

R Takahashi - Mathematische Zeitschrift, 2023 - Springer
In this paper, we prove Faltings' annihilator theorem for complexes over a CM-excellent ring.
As an application, we give a complete classification of the t-structures of the bounded …

Classifying subcategories of modules

M Hovey - Transactions of the American Mathematical Society, 2001 - ams.org
Let $ R $ be the quotient of a regular coherent commutative ring by a finitely generated
ideal. In this paper, we classify all abelian subcategories of finitely presented $ R $-modules …

On localizing subcategories of derived categories

R Takahashi - Journal of mathematics of Kyoto University, 2009 - projecteuclid.org
Let $ A $ be a commutative noetherian ring. In this paper, we interpret localizing
subcategories of the derived category of $ A $ by using subsets of Spec $ A $ and …
