四元数代数上CM型的周期恒等式

Period identities of CM forms on quaternion algebras

Charlotte Chan

摘要:

Waldspurger公式给出了GL(2)上的自守表示的环面周期的范数与扭曲的L函数之间的恒等式。对于固定二次扩张的任何两个Hecke特征标,可以考虑两个环面周期来自于对一个特征标的自守归纳的积分。因为相应的L-函数一致,所以这些周期(的范数)--出现在不同的四元数代数上--是密切相关的。在本文中,我们给出了一个直接的证明之间的一个明确的身份环面周期本身。

英文摘要:

Waldspurger's formula gives an identity between the norm of a torus period and an L-function of the twist of an automorphic representation on GL(2). For any two Hecke characters of a fixed quadratic extension, one can consider the two torus periods coming from integrating one character against the automorphic induction of the other. Because the corresponding L-functions agree, (the norms of) these periods---which occur on different quaternion algebras---are closely related. In this paper, we give a direct proof of an explicit identity between the torus periods themselves.
