关于自守形式的有限性定理

On finiteness theorems for automorphic forms

Takuya Yamauchi

AI总结:

本文研究 Shimura 数据上自守形式分次空间的有限性,借助自反层与高阶 Koecher 原理实现整体截面,并给出仅基于 Chai-Faltings 结果的 Siegel 模形式精细版本。

摘要:

本文针对满足合理条件、从而涵盖许多重要情形的任意 Shimura 数据 $(G,\mathcal{D})$,证明了若干有限性定理,对象是由 $\mathcal{D}$ 上某些权重的自守形式构成的任意分次向量空间,而这些形式定义在 $X$ 上具有正平行权重的自守形式分次环之上。我们还讨论了可在其上工作的整基环。为将自守形式实现为最小紧化上某些凝聚层的整体截面,我们使用自反层概念以及 Kai-Wen Lan 提出的高阶 Koecher 原理。此外,我们仅利用 Chai-Faltings 的结果,给出了 Siegel 模形式有限性结果的更精细版本。

英文摘要:

In this paper, for any Shimura datum $(G,\mathcal{D})$ satisfying reasonable conditions so that many interesting cases satisfy, we prove some finiteness theorems for any graded vector space consisting of automorphic forms on $\mathcal{D}$ of some weights over the graded ring of automorphic forms on $X$ with positive parallel weights. We also discuss the integral base ring which we can work on. To realize automorphic forms as global sections on some coherent sheaves on the minimal compactification, we use the notion of reflexive sheaves and higher Koecher principle due to Kai-Wen Lan. Further, we give a more finer version of finiteness results for Siegel modular forms by using only the results of Chai-Faltings.
