The Prym map on divisors, and the slope of A_5
Samuel Grushevsky, Riccardo Salvati Manni, Klaus Hulek
In this paper we compute the pullback of divisor classes under the Prym map (extended to the boundary), and apply this result to get a lower bound on the slope of effective divisor…
Principally polarized semi-abelic varieties of small torus rank, and the Andreotti-Mayer loci
Samuel Grushevsky, Klaus Hulek
We obtain, by a direct computation, explicit descriptions of all principally polarized semi-abelic varieties of torus rank up to 3. We describe the geometry of their symmetric thet…
Cohomology of the second Voronoi compactification of A_4
Klaus Hulek, Orsola Tommasi
In this paper we compute the cohomology groups of the second Voronoi compactification of the moduli space of abelian fourfolds in all degrees with the exception of the middle degre…
The class of the locus of intermediate Jacobians of cubic threefolds
Samuel Grushevsky, Klaus Hulek
We study the locus of intermediate Jacobians of cubic threefolds within the moduli space of complex principally polarized abelian fivefolds, and its generalization to arbitrary gen…
