O'Grady's tenfolds from stable bundles on hyper-K\"ahler fourfolds

Algebraic Geometry 2025-01-17 v2

Abstract

We provide a modular construction of the Laza--Sacc\`a--Voisin compactification of the intermediate Jacobian fibration of a cubic fourfold. Additionally, we construct infinitely many 2020-dimensional families of polarized hyper-K\"ahler manifolds of type OG10, realized as moduli spaces of stable bundles on hyper-K\"ahler manifolds of type K3[2]\mathrm{K3}^{[2]}.
