Degenerations of (1,3) abelian surfaces and Kummer surfaces
K. Hulek, I. Nieto, G. K. Sankaran
We continue our study of the geometry of Nieto's quintic threefold, looking at degenerate surfaces that correspond to certain loci and showing how they arise from a toroidal compac…
Heisenberg-invariant Kummer surfaces
K. Hulek, I. Nieto, G. K. Sankaran
We study the geometry of Nieto's quintic threefold (Barth & Nieto, J. Alg. Geom. 3, 1994) and the Kummer and abelian surfaces that correspond to special loci.
Nef Divisors on Moduli Spaces of Abelian Varieties
Klaus Hulek
We determine the cone of nef divisors on the Voronoi compactification A_g^* of the moduli space A_g of principally polarized abelian varieties of dimension g for genus g=2,3. As a…
A Remark on the Geometry of Elliptic Scrolls and Bielliptic Surfaces
C. Ciliberto, K. Hulek
The union of two quintic elliptic scrolls in P^4 intersecting transversally along an elliptic normal quintic curve is a singular surface Z which behaves numerically like a biellipt…
