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…

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…
