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…

Rank one Eisenstein cohomology of local systems on the moduli space of abelian varieties
Gerard van der Geer
We give a formula for the Eisenstein cohomology of local systems on the partial compactification of the moduli of principally polarized abelian varieties given by rank 1 degenerati…

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…
