模L函数的裁剪Euler因子

Cropping Euler factors of modular L-functions

J. Gonzalez, J. Jimenez, J. -C. Lario

摘要:

根据Birch和Swinnerton-Dyer定理,如果A/Q是一个阿贝尔簇,那么它的L-函数必须捕获A的算术性质的实质部分。最小数域L,其中A定义了它的所有自同态,也必须有一个角色。本文在模阿贝尔簇A_f/Q对应于模群Gamma_1(N)的权为2的新形式的特殊情况下,讨论了这两个对象之间的关系。具体地说,我们的目标是将L(A_f/Q,s)在s = 1时的阶与由在L中完全分裂的素数集裁剪的Euler积联系起来。当f有复乘时,我们得到的结果是完全的,而在没有CM的情况下,我们的结果依赖于Sato-Tate分布的收敛速率。

英文摘要:

According to the Birch and Swinnerton-Dyer conjectures, if A/Q is an abelian variety then its L-function must capture substantial part of the arithmetic properties of A. The smallest number field L where A has all its endomorphisms defined must also have a role. This article deals with the relationship between these two objects in the specific case of modular abelian varieties A_f/Q associated to weight 2 newforms for the modular group Gamma_1(N). Specifically, our goal is to relate the order of L(A_f/Q,s) at s = 1 with Euler products cropped by the set of primes that split completely in L. The results we obtain for the case when f has complex multiplication are complete, while in the absence of CM, our results depend on the rate of convergence in Sato-Tate distributions.
