Siegel modular forms of degree three and the cohomology of local systems
Jonas Bergström, Carel Faber, Gerard van der Geer

Cycle classes on the moduli of K3 surfaces in positive characteristic
Torsten Ekedahl, Gerard van der Geer
This paper provides explicit closed formulas in terms of tautological classes for the cycle classes of the height and Artin invariant strata in families of K3 surfaces. The proof i…
