[HTML][HTML] Categorical Torelli theorems: results and open problems
L Pertusi, P Stellari - Rendiconti del Circolo Matematico di Palermo Series …, 2023 - Springer
We survey some recent results concerning the so called Categorical Torelli problem. This is
to say how one can reconstruct a smooth projective variety up to isomorphism, by using the …

Derived categories of hearts on Kuznetsov components
We prove a general criterion that guarantees that an admissible subcategory KK of the
derived category of an abelian category is equivalent to the bounded derived category of the …

Categorical resolutions of filtered schemes
T De Deyn - arXiv preprint arXiv:2309.08330, 2023 - arxiv.org
We give an alternative proof of the theorem by Kuznetsov and Lunts stating that any
separated scheme of finite type over a field of characteristic zero admits a categorical …

[HTML][HTML] Morita theorem for hereditary Calabi-Yau categories
N Hanihara - Advances in Mathematics, 2022 - Elsevier
We give a structure theorem for Calabi-Yau triangulated category with a hereditary cluster
tilting object. We prove that an algebraic d-Calabi-Yau triangulated category with a d-cluster …

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 …

The Derived Auslander-Iyama Correspondence
We work over a perfect field. Recent work of the third-named author established a Derived
Auslander Correspondence that relates finite-dimensional self-injective algebras that are …

Formality and strongly unique enhancements
A Lorenzin - arXiv preprint arXiv:2204.09527, 2022 - arxiv.org
Inspired by the intrinsic formality of graded algebras, we prove a necessary and sufficient
condition for strongly uniqueness of DG-enhancements. This approach offers a …

A Derived Gabriel–Popescu Theorem for t-Structures via Derived Injectives
F Genovese, J Ramos González - International Mathematics …, 2023 - academic.oup.com
We prove a derived version of the Gabriel–Popescu theorem in the framework of dg-
categories and t-structures. This exhibits any pretriangulated dg-category with a suitable t …

Localizations of the category of categories and internal Homs over a ring
A Canonaco, M Ornaghi, P Stellari - arXiv preprint arXiv:2404.06610, 2024 - arxiv.org
We show that, over an arbitrary commutative ring, the localizations of the categories of dg
categories, of unital and of strictly unital $ A_\infty $ categories with respect to the …

Versal dg deformation of Calabi--Yau manifolds
H Morimura - arXiv preprint arXiv:2111.11778, 2021 - arxiv.org
We prove the equivalence of the deformation theory for a higher dimensional Calabi--Yau
manifold and that for its dg category of perfect complexes by giving a natural isomorphism of …
