Siegel modular forms of genus 2 and level 2: cohomological computations and conjectures
Jonas Bergström, Carel Faber, Gerard van der Geer
We study the cohomology of certain local systems on moduli spaces of principally polarized abelian surfaces with a level 2 structure. The trace of Frobenius on the alternating sum…
Prym varieties associated to graphs
Rudi Salomon
We present a Prym construction which associates abelian varieties to vertex-transitive strongly regular graphs. As an application we construct Prym-Tyurin varieties of arbitrary ex…
The Galois closure of the Garcia-Stichtenoth tower
Alexey Zaytsev
We describe the Galois closure of the Garcia-Stichtenoth tower and prove that it is optimal.
Cycle Classes of the E-O Stratification on the Moduli of Abelian Varieties
Torsten Ekedahl, Gerard van der Geer
We introduce a stratification on the space of symplectic flags on the de Rham bundle of the universal principally polarized abelian variety in positive characteristic and study its…
On the geometry of the Calogero-Moser system
Wim Couwenberg, Gert Heckman, Eduard Looijenga
We discuss a special eigenstate of the quantized periodic Calogero-Moser system associated to a root system. This state has the property that its eigenfunctions, when regarded as m…
The Euler characteristic of local systems on the moduli of genus 3 hyperelliptic curves
Gilberto Bini, Gerard van der Geer
For a partition of non-negative integers, we calculate the Euler characteristic of the local system on the moduli space of genus 3 hy…
