AI中文摘要:
利用近期在Shimura簇的积分典范模型中使用syntomic方法取得的进展,我们给出了Scholze关于$p$-可除群形变空间的Langlands--Kottwitz方法论文中方法的推广。具体而言,我们定义了局部测试函数$\u03d5^{\u0047,\u03bc}_{\u03c4,h}$的类似物,在完全一般性下,证明了它们满足合理的调和-解析性质,并由此导出了坏约化Shimura簇上同调中Galois-Hecke作用的迹公式。此外,我们利用这些新的局部测试函数以及Fargues--Scholze的工作,提出了一个更稳健且无条件版本的Scholze--Shin猜想。在此过程中,我们研究了Drinfeld和Gardner--Madapusi的$(\u0047,\u03bc)$-孔径,特别证明了在好的基上,这样的$(\u0047,\u03bc)$-孔径所携带的信息不超过Fontaine--Laffaille理论的Tannakian版本,并给出了$(\u0047,\u03bc)$-孔径的普适形变的非常明确的描述。
英文摘要:
Using recent advances in the integral canonical models of Shimura varieties using syntomic methods, we give an extension of the Langlands--Kottwitz--Scholze method from Scholze's paper on the Langlands--Kottwitz method for deformation spaces of $p$-divisible groups. Namely, we define analogues $ϕ^{\mathcal{G},μ}_{τ,h}$ of the local test functions from op. cit. in full generality, show they satisfy reasonable harmonic-analytic properties, and give rise to trace formulae for the Galois-Hecke action on the cohomology of Shimura varieties of bad reduction. Additionally, we use these new local test functions and the work of Fargues--Scholze to state a more robust and unconditional version of the Scholze--Shin conjecture. Along the way we study the $(\mathcal{G},μ)$-apertures of Drinfeld and Gardner--Madapusi, in particular showing that such $(\mathcal{G},μ)$-apertures carry no more information than a Tannakian version of Fontaine--Laffaille theory, at least over nice bases, and give a very explicit description of the universal deformations of $(\mathcal{G},μ)$-apertures.
