菱形上的局部系与$p$ -adic向量丛

Local systems on diamonds and $p$-adic vector bundles

Lucas Mann, Annette Werner

摘要:

我们使用Scholze的钻石框架,以获得新的见解$p$ -adic向量丛和本地系统之间的对应关系。这样的对应关系出现在$p$ -adic Simpson理论中希格斯场消失的情况下。在本文中,我们提供了一个详细的分析钻石的局部系统的étale,pro-étale,和$v$ -拓扑,并研究了所有三个拓扑的结构层的问题。应用于$\mathbb{C}_p$上有限型的真adic空间,这使我们能够证明具有积分模型的$\mathbb{C}_p$ -局部系统与$v$ -结构层下的模之间的范畴等价性,其中模每个$p^n$可以在真覆盖上平凡化.的灵活性的$v$ -拓扑连同下降结果的整体模型的本地系统,使我们能够证明,平凡化条件的模块类别可以检查任何正常的适当覆盖。这一结果导致的平行运输理论的Deninger和第二作者的向量丛与数值平坦减少正常覆盖的延伸。

英文摘要:

We use Scholze's framework of diamonds to gain new insights in correspondences between $p$-adic vector bundles and local systems. Such correspondences arise in the context of $p$-adic Simpson theory in the case of vanishing Higgs fields. In the present paper we provide a detailed analysis of local systems on diamonds for the étale, pro-étale, and the $v$-topology, and study the structure sheaves for all three topologies in question. Applied to proper adic spaces of finite type over $\mathbb{C}_p$ this enables us to prove a category equivalence between $\mathbb{C}_p$-local systems with integral models, and modules under the $v$-structure sheaf which modulo each $p^n$ can be trivialized on a proper cover. The flexibility of the $v$-topology together with a descent result on integral models of local systems allows us to prove that the trivializability condition in the module category may be checked on any normal proper cover. This result leads to an extension of the parallel transport theory by Deninger and the second author to vector bundles with numerically flat reduction on a proper normal cover.
