Cohomology of the moduli space of degree two Enriques surfaces
Mauro Fortuna
We compute the intersection Betti numbers of the GIT model of the moduli space of numerically polarized Enriques surfaces of degree 2. The strategy of the cohomological calculation…

Unirational moduli spaces of some elliptic K3 surfaces
Mauro Fortuna, Michael Hoff, Giacomo Mezzedimi
We show that the moduli space of -polarized K3 surfaces is unirational for and , and for other several values of $…

The Kodaira dimension of some moduli spaces of elliptic K3 surfaces
Mauro Fortuna, Giacomo Mezzedimi
We study the moduli spaces of elliptic K3 surfaces of Picard number at least 3, i.e. -polarized K3 surfaces. Such moduli spaces are proved to be of gen…

Cohomology of the moduli space of non-hyperelliptic genus four curves
Mauro Fortuna
We compute the intersection Betti numbers of the GIT model of the moduli space of Brill-Noether-Petri general curves of genus 4. This space was shown to be the final non-trivial lo…
