Note on tautological classes of moduli of K3 surfaces
Gerard van der Geer, Toshiyuki Katsura
We prove some cycle relations on moduli of K3 surfaces
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…
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…
Cycles Representing The Top Chern Class of the Hodge Bundle on the Moduli Space of Abelian Varieties
Torsten Ekedahl, Gerard van der Geer
We give a generalization to higher genera of the famous formula for genus 1. We also compute the classes of certain strata in the Satake compactification as elements of th…
Complete subvarieties of moduli spaces and the Prym map
Carel Faber, Gerard van der Geer
We prove that in characteristic p>0 the locus of stable curves of p-rank at most f is pure of codimension g-f in the moduli space of stable curves. Then we consider the Prym map an…
The order of the top Chern class of the Hodge bundle on the moduli space of abelian varieties
Torsten Ekedahl, Gerard van der Geer
We give upper and lower bounds for the order of the top Chern class of the Hodge bundle on the moduli space of principally polarized abelian varieties.
