Abelian surfaces with two plane cubic curve fibrations and Calabi-Yau threefolds
Klaus Hulek, Kristian Ranestad
(1,d)-polarized abelian surfaces in P^(d-1) with two plane cubic curve fibrations lie in two elliptic P^2-scrolls. The union of these scrolls form a reducible Calabi-Yau 3-fold. In…

The geometry of Siegel modular varieties
K. Hulek, G. K. Sankaran
This is a survey article about Siegel modular varieties over the complex numbers. It is written mostly from the point of view of moduli of abelian varieties, especially surfaces. W…

The Modular Form of the Barth-Nieto Quintic
V. Gritsenko, K. Hulek
Barth and Nieto have found a remarkable quintic threefold which parametrizes Heisenberg invariant Kummer surfaces which belong to abelian surfaces with a (1,3)-polarization and a l…
