约化子群上自守形式的周期

Periods of automorphic forms over reductive subgroups

Michał Zydor

摘要:

给出了任意约化子群$G' \subset G$上的群$G$上的自守形式的周期积分的正则化方法.作为结果,我们得到了一个明确的$G'(\mathbb{A})$不变的功能空间上的自守形式的$G$,其指数避免某些指定的超平面。我们还给出了自守形式的周期积分按指数收敛的一个充要条件。

英文摘要:

We present a regularization procedure of period integrals of automorphic forms on a group $G$ over an arbitrary reductive subgroup $G' \subset G$. As a consequence we obtain an explicit $G'(\mathbb{A})$-invariant functional on the space of automorphic forms on $G$ whose exponents avoid certain prescribed hyperplanes. We also provide a necessary and sufficient condition for convergence of period integrals of automorphic forms in terms of their exponents.
