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 …

Stability conditions and moduli spaces for Kuznetsov components of Gushel–Mukai varieties

A Perry, L Pertusi, X Zhao - Geometry & Topology, 2023 - msp.org
We prove the existence of Bridgeland stability conditions on the Kuznetsov components of
Gushel–Mukai varieties, and describe the structure of moduli spaces of Bridgeland …

The generalized Franchetta conjecture for some hyper-Kähler varieties, II

L Fu, R Laterveer, C Vial - Journal de l'École polytechnique …, 2021 - numdam.org
We prove the generalized Franchetta conjecture for the locally complete family of hyper-
Kähler eightfolds constructed by Lehn–Lehn–Sorger–van Straten (LLSS). As a corollary, we …

Birational geometry of the intermediate Jacobian fibration of a cubic fourfold

G Saccà - Geometry & Topology, 2023 - msp.org
We show that the intermediate Jacobian fibration associated to any smooth cubic fourfold X
admits a hyper-Kähler compactification J (X) with a regular Lagrangian fibration π: J→ ℙ 5 …

[HTML][HTML] On the transcendental lattices of Hyper-Kähler manifolds

B Piroddi, ÁDR Ortiz - Journal of Pure and Applied Algebra, 2025 - Elsevier
We introduce the notion of a Hyper-Kähler manifold X induced by a Hodge structure of K3-
type. We explore this notion for the known deformation types of Hyper-Kähler manifolds …

On the motive of O'Grady's ten-dimensional hyper-Kähler varieties

S Floccari, L Fu, Z Zhang - Communications in Contemporary …, 2021 - World Scientific
We investigate how the motive of hyper-Kähler varieties is controlled by weight-2 (or surface-
like) motives via tensor operations. In the first part, we study the Voevodsky motive of …

Conics on Gushel-Mukai fourfolds, EPW sextics and Bridgeland moduli spaces

H Guo, Z Liu, S Zhang - arXiv preprint arXiv:2203.05442, 2022 - arxiv.org
We identify the double dual EPW sextic $\widetilde {Y} _ {A^{\perp}} $ and the double EPW
sextic $\widetilde {Y} _A $, associated with a very general Gushel-Mukai fourfold $ X $, with …

O'Grady tenfolds as moduli spaces of sheaves

C Felisetti, F Giovenzana, A Grossi - Forum of Mathematics, Sigma, 2024 - cambridge.org
We give a lattice-theoretic characterization for a manifold of type associated to any smooth
cubic fourfold. Moreover, we determine when a birational transformation is induced by an …
