Enumerative invariants and wall-crossing formulae in abelian categories

D Joyce - arXiv preprint arXiv:2111.04694, 2021 - arxiv.org
Enumerative invariants in Algebraic Geometry'count'$\tau $-(semi) stable objects $ E $ with
fixed topological invariants $[E]= a $ in some geometric problem, using a virtual class $[{\cal …

Stability conditions on Kuznetsov components

A Bayer, M Lahoz, E Macrì, P Stellari - arXiv preprint arXiv:1703.10839, 2017 - arxiv.org
We introduce a general method to induce Bridgeland stability conditions on semiorthogonal
components of triangulated categories. In particular, we prove the existence of Bridgeland …

Hyper-kähler manifolds

O Debarre - Milan Journal of Mathematics, 2022 - Springer
The aim of this introductory survey is to acquaint the reader with important objects in
complex algebraic geometry: K3 surfaces and their higher-dimensional analogs, hyper …

The integral Hodge conjecture for two-dimensional Calabi–Yau categories

A Perry - Compositio Mathematica, 2022 - cambridge.org
We formulate a version of the integral Hodge conjecture for categories, prove the conjecture
for two-dimensional Calabi–Yau categories which are suitably deformation equivalent to the …

Moduli spaces of stable objects in Enriques categories

A Perry, L Pertusi, X Zhao - arXiv preprint arXiv:2305.10702, 2023 - arxiv.org
We study moduli spaces of stable objects in Enriques categories by exploiting their relation
to moduli spaces of stable objects in associated K3 categories. In particular, we settle the …

Purity and 2-Calabi-Yau categories

B Davison - arXiv preprint arXiv:2106.07692, 2021 - arxiv.org
For various 2-Calabi-Yau categories $\mathscr {C} $ for which the stack of objects
$\mathfrak {M} $ has a good moduli space $ p\colon\mathfrak {M}\rightarrow\mathcal {M} …

Derived categories of hearts on Kuznetsov components

C Li, L Pertusi, X Zhao - Journal of the London Mathematical …, 2023 - Wiley Online Library
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 …

Moduli spaces and geometric invariant theory: old and new perspectives

V Hoskins - arXiv preprint arXiv:2302.14499, 2023 - arxiv.org
Many moduli spaces are constructed as quotients of group actions; this paper surveys the
classical theory, as well as recent progress and applications. We review geometric invariant …

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 …
