Strict polynomial functors and multisets
Torsten Ekedahl, Pelle Salomonsson
We prove a generalisation to any characteristic of a result of Macdonald that describes strict polynomial functors in characteristic zero in terms of representations of the groupoi…
Kac-Moody algebras and the cde-triangle
Torsten Ekedahl
This is the written version of a talk at the conference on ``Non-commutative geometry and representation theory in mathematical physics'' held in Karlstad, Sweden, 5--10 July, 2004…
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…
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…
