Stability conditions in families

A Bayer, M Lahoz, E Macrì, H Nuer, A Perry… - … mathématiques de l' …, 2021 - Springer
We develop a theory of Bridgeland stability conditions and moduli spaces of semistable
objects for a family of varieties. Our approach is based on and generalizes previous work by …

Multiple cover formulas for K3 geometries, wall-crossing, and Quot schemes

G Oberdieck - arXiv preprint arXiv:2111.11239, 2021 - arxiv.org
Let $ S $ be a K3 surface. We study the reduced Donaldson-Thomas theory of the cap
$(S\times\mathbb {P}^ 1)/S_ {\infty} $ by a second cosection argument. We obtain four main …

Rank DT theory from rank

S Feyzbakhsh, RP Thomas - arXiv preprint arXiv:2103.02915, 2021 - arxiv.org
Fix a Calabi-Yau 3-fold $ X $ satisfying the Bogomolov-Gieseker conjecture of Bayer-Macr\i-
Toda, such as the quintic 3-fold. We express Joyce's generalised DT invariants counting …

Enumerative mirror symmetry for moduli spaces of Higgs bundles and S-duality

D Nesterov - arXiv preprint arXiv:2302.08379, 2023 - arxiv.org
We derive conjectures, called genus 1 Enumerative mirror symmetry for moduli spaces of
Higgs bundles, which relate curve-counting invariants of moduli spaces of Higgs $\mathrm …

Stability conditions on free abelian quotients

H Dell - arXiv preprint arXiv:2307.00815, 2023 - arxiv.org
We study slope-stable vector bundles and Bridgeland stability conditions on varieties which
are a quotient of a smooth projective variety by a finite abelian group $ G $ acting freely. We …

The period-index conjecture for abelian threefolds and Donaldson-Thomas theory

J Hotchkiss, A Perry - arXiv preprint arXiv:2405.03315, 2024 - arxiv.org
We prove the period-index conjecture for unramified Brauer classes on abelian threefolds.
To do so, we develop a theory of reduced Donaldson-Thomas invariants for 3-dimensional …

Stability Conditions on

D Wu, N Zhang - arXiv preprint arXiv:2408.00519, 2024 - arxiv.org
We construct a subset of the space of stability conditions for any projective threefold with an
ample polarization that satisfies a certain Bogomolov-Gieseker inequality to refine the result …

The stability manifold of

F Haiden, B Sung - arXiv preprint arXiv:2410.08028, 2024 - arxiv.org
We determine a full component of the space of stability conditions on $ D^ b (E^ 3) $ where
$ E $ is an elliptic curve without complex multiplication. The component has complex …

Stability conditions and group actions

H Dell - 2024 - era.ed.ac.uk
We study slope-stable vector bundles and Bridgeland stability conditions on varieties which
are a quotient of a smooth projective variety by a finite group G acting freely. We show that …
