Extremal divisors on moduli spaces of K3 surfaces
Ignacio Barros, Laure Flapan, Riccardo Zuffetti
We establish criteria for when Noether--Lefschetz divisors generate an extremal ray in the cone of pseudoeffective divisors of an orthogonal modular variety. In particular, we exhi…
Equivariant Kuznetsov components for cubic fourfolds with a symplectic involution
Laure Flapan, Sarah Frei, Lisa Marquand
We study the equivariant Kuznetsov component of a general cubic fourfold with a symplectic involution. We show that is equivalent to the d…
Cones of Noether-Lefschetz divisors and moduli spaces of hyperkähler manifolds
Ignacio Barros, Pietro Beri, Laure Flapan +1
We give a general formula for generators of the NL-cone, the cone of effective linear combinations of irreducible components of Noether-Lefschetz divisors, on an orthogonal modular…
The geometry of antisymplectic involutions, II
Laure Flapan, Emanuele Macrì, Kieran G. O'Grady +1
We continue our study of fixed loci of antisymplectic involutions on projective hyper-Kähler manifolds of -type induced by an ample class of square 2 in the Beau…
Kodaira dimension of moduli spaces of hyperkähler varieties
Ignacio Barros, Pietro Beri, Emma Brakkee +1
We study the Kodaira dimension of moduli spaces of polarized hyperkähler varieties deformation equivalent to the Hilbert scheme of points on a K3 surface or to O'Grady's ten dimens…
Period integrals and Hodge modules
Laure Flapan, Robin Walters, Xiaolei Zhao
We define a map attached to any polarized Hodge module such that the restriction of to a locus on which is a variation of Hodge structures i…
