Harder-Narasimhan地层和$p$ -adic周期域

Harder-Narasimhan strata and $p$-adic period domains

Xu Shen

摘要:

本文利用Festies-Fontaine曲线上$G$ -丛的修正理论,重新研究了极小$p$ -adic旗簇上的Harder-Narasimhan分层.我们将Harder-Narasimhan地层与Caraiani-Scholze介绍的牛顿地层进行了比较。作为结果,我们得到了关于完全Hodge-Newton可分解对的$p$ -adic Hodge-Tate周期域的进一步等价条件。此外,通过考虑相关的$B_{dR}^+$ -仿射Schubert簇,我们将这些结果推广到任意余特征标的情形.利用Hodge-Tate周期映射,我们构造了Shimura簇及其局部类似物的$p$ -adic几何.

英文摘要:

We revisit the Harder-Narasimhan stratification on a minuscule $p$-adic flag variety, by the theory of modifications of $G$-bundles on the Fargues-Fontaine curve. We compare the Harder-Narasimhan strata with the Newton strata introduced by Caraiani-Scholze. As a consequence, we get further equivalent conditions in terms of $p$-adic Hodge-Tate period domains for fully Hodge-Newton decomposable pairs. Moreover, we generalize these results to arbitrary cocharacters case by considering the associated $B_{dR}^+$-affine Schubert varieties. Applying Hodge-Tate period maps, our constructions give applications to $p$-adic geometry of Shimura varieties and their local analogues.
