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 models of moduli spaces of coherent sheaves on the projective plane

C Li, X Zhao - Geometry & Topology, 2019 - msp.org
We study the birational geometry of moduli spaces of semistable sheaves on the projective
plane via Bridgeland stability conditions. We show that the entire MMP of their moduli …

Motives of moduli spaces on K3 surfaces and of special cubic fourfolds

TH Bülles - manuscripta mathematica, 2020 - Springer
For any smooth projective moduli space M of Gieseker stable sheaves on a complex
projective K3 surface (or an abelian surface) S, we prove that the Chow motive h (M) h (M) …

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 …

Chow ring and gonality of general abelian varieties

C Voisin - Annales Henri Lebesgue, 2018 - numdam.org
We study the (covering) gonality of abelian varieties and their orbits of zero-cycles for
rational equivalence. We show that any orbit for rational equivalence of zerocycles of degree …

On the Lefschetz standard conjecture for Lagrangian covered hyper-Kähler varieties

C Voisin - Advances in Mathematics, 2022 - Elsevier
We investigate the Lefschetz standard conjecture for degree 2 cohomology of hyper-Kähler
manifolds admitting a covering by Lagrangian subvarieties. In the case of a Lagrangian …

Derived categories of surfaces, O'Grady's filtration, and zero-cycles on holomorphic symplectic varieties

J Shen, Q Yin, X Zhao - Compositio Mathematica, 2020 - cambridge.org
Moduli spaces of stable objects in the derived category of a-group of the moduli space of
stable objects. We discuss its connection with Voisin's recent proposal via constant cycle …

Bloch's conjecture for (anti-) autoequivalences on K3 surfaces

Z Li, X Yu, R Zhang - arXiv preprint arXiv:2305.10078, 2023 - arxiv.org
In this paper, we study Bloch's conjecture for zero cycles on K3 surfaces and hyper-K\" ahler
varieties. We prove Bloch's conjecture for reflexive autoequivalences on K3 surfaces. This …

CATEGORIES, ONE-CYCLES ON CUBIC FOURFOLDS, AND THE BEAUVILLE–VOISIN FILTRATION

J Shen, Q Yin - Journal of the Institute of Mathematics of Jussieu, 2020 - cambridge.org
We explore the connection between K3 categories and 0-cycles on holomorphic symplectic
varieties. In this paper, we focus on Kuznetsov's noncommutative K3 category associated to …

On the birational motive of hyper-Kähler varieties

C Vial - Journal de Mathématiques Pures et Appliquées, 2022 - Elsevier
We introduce a new ascending filtration, that we call the co-radical filtration in analogy with
the basic theory of co-algebras, on the Chow groups of pointed smooth projective varieties …
