$\mathrm{SL}_2$上的几乎全纯自守形式

Nearly holomorphic automorphic forms on $\mathrm{SL}_2$

Shuji Horinaga

摘要:

定义了$\mathbb{Q}$上的连通约化群$G$上的几乎全纯自守形式空间,使得齐性空间$G(\mathbb{R})^1/ K_\infty^\circ$是Hermite对称空间.通过Pitale,Saha和Schmidt的研究,给出了出现在几乎全纯椭圆模形式空间和Siegel模$2$次形式空间中的不可分解$(\mathfrak{g},K_\infty)$ -模的分类.本文研究了几乎全纯Hilbert模形式空间中Adele群$G(\mathbb{A}_\mathbb{Q})$的整体表示.在椭圆模形式的情形下,本文的结果是Pitale,Saha和Schmidt的结果的推广.

英文摘要:

We define the space of nearly holomorphic automorphic forms on a connected reductive group $G$ over $\mathbb{Q}$ such that the homogeneous space $G(\mathbb{R})^1/ K_\infty^\circ$ is a Hermitian symmetric space. By Pitale, Saha and Schmidt's study, there are the classification of indecomposable $(\mathfrak{g},K_\infty)$-modules which occur in the space of nearly holomorphic elliptic modular forms and Siegel modular forms of degree $2$. This paper studies global representations of the adele group $G(\mathbb{A}_\mathbb{Q})$ which occur in the space of nearly holomorphic Hilbert modular forms. In the case of elliptic modular forms, the result of this paper is an adelization of Pitale, Saha and Schmidt's result.
