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 $l amb d a = {l amb d a_{1} \geq λ_{2} \geq λ_{3}}$ of non-negative integers, we calculate the Euler characteristic of the local system $V_{λ}$ 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 $12 λ = δ$ for genus 1. We also compute the classes of certain strata in the Satake compactification as elements of th…
