On étudie la relation entre le -rang des variétés abéliennes en caractéristique et la stratification de Kottwitz-Rapoport de la fibre spéciale en de l’espace de module des variétés abéliennes principalement polarisées avec structure de niveau de type Iwahori en . En particulier, on démontre la densité du lieu ordinaire dans cette fibre spéciale.
We study the relation between the -rank of abelian varieties in characteristic and the Kottwitz-Rapoport’s stratification of the special fiber modulo of the moduli space of principally polarized abelian varieties with Iwahori type level structure on . In particular, the density of the ordinary locus in that special fiber is proved.
