Kuznetsov's Fano threefold conjecture via K3 categories and enhanced group actions

A Bayer, A Perry - Journal für die reine und angewandte Mathematik …, 2023 - degruyter.com
We settle the last open case of Kuznetsov's conjecture on the derived categories of Fano
threefolds. Contrary to the original conjecture, we prove the Kuznetsov components of …

Curve counting on the Enriques surface and the Klemm-Mari\~{n} o formula

G Oberdieck - arXiv preprint arXiv:2305.11115, 2023 - arxiv.org
We determine the Gromov-Witten invariants of the local Enriques surfaces for all genera and
curve classes and prove the Klemm-Mari\~{n} o formula. In particular, we show that the …

Derived categories of hyper-Kähler manifolds: extended Mukai vector and integral structure

T Beckmann - Compositio Mathematica, 2023 - cambridge.org
We introduce a linearised form of the square root of the Todd class inside the Verbitsky
component of a hyper-Kähler manifold using the extended Mukai lattice. This enables us to …

Fusion-equivariant stability conditions and Morita duality

H Dell, E Heng, AM Licata - arXiv preprint arXiv:2311.06857, 2023 - arxiv.org
Given a triangulated category $ D $ with an action of a fusion category $ C $, we study the
moduli space $ Stab_ {C}(D) $ of fusion-equivariant Bridgeland stability conditions on $ D …

Equivariant categories of symplectic surfaces and fixed loci of Bridgeland moduli spaces

T Beckmann, G Oberdieck - arXiv preprint arXiv:2006.13899, 2020 - arxiv.org
Given an action of a finite group $ G $ on the derived category of a smooth projective variety
$ X $ we relate the fixed loci of the induced $ G $-action on moduli spaces of stable objects …

Three approaches to a categorical Torelli theorem for cubic threefolds of non-Eckardt type via the equivariant Kuznetsov components

S Casalaina-Martin, X Hu, X Lin, S Zhang… - arXiv preprint arXiv …, 2024 - arxiv.org
Let $ Y $ be a cubic threefold with a non-Eckardt type involution $\tau $. Our first main result
is that the $\tau $-equivariant category of the Kuznetsov component $\mathcal {K} u …

Stability conditions on crepant resolutions of quotients of product varieties

A Perry, S Shah - arXiv preprint arXiv:2404.09121, 2024 - arxiv.org
We construct stability conditions on crepant resolutions of quotients of certain product
varieties, giving as a special case the first examples of stability conditions on strict Calabi …

Equivariant Kuznetsov Components of Certain Cubic Fourfolds

X Hu - arXiv preprint arXiv:2312.17392, 2023 - arxiv.org
Let $ M $ denote a specific cubic fourfold that accommodates a group action by $\mathbb
{Z}/3\mathbb {Z} $. Through utilization of derived Mckay correspondence, we present a new …

On two families of Enriques categories over K3 surfaecs

Z Liu - arXiv preprint arXiv:2412.06921, 2024 - arxiv.org
This article studies the moduli spaces of semistable objects related to two families of
Enriques categories over K3 surfaces, coming from quartic double solids and special Gushel …
