摘要:
研究了特征$p$中阿贝尔簇的$p$秩与$p$上具有Iwahori型水平结构的主极化阿贝尔簇的模空间的特殊纤维模$p$的Kottwitz-Rapoport分层之间的关系.特别证明了该特殊纤维中寻常轨迹的密度。
英文摘要:
We study the relation between the $p$-rank of abelian varieties in characteristic $p$ and the Kottwitz-Rapoport's stratification of the special fiber modulo $p$ of the moduli space of principally polarized abelian varieties with Iwahori type level structure on $p$. In particular, the density of the ordinary locus in that special fiber is proved.
