Dirichlet L函数的同时非零性

Simultaneous non-vanishing for Dirichlet L-functions

Raphael Zacharias

摘要:

本文推广了Fouvry,Kowalski和Michel关于模形式的Hecke特征值与代数迹函数之间的相关性的工作,建立了模L函数在中心点s = 1/2处的广义三阶矩和素数模q的渐近公式.作为应用,我们利用我们最近关于Dirichlet L函数四阶矩的软化的结果,导出了对于任何模q的乘法特征标对$(ω_1,ω_2)$,存在正的$χ$(mod q)的比例,使得$L(χ, 1/2 ), L(χω_1, 1/2 )$和$L(χω_2, 1/2)$同时不太小.

英文摘要:

We extend the work of Fouvry, Kowalski and Michel on correlation between Hecke eigenvalues of modular forms and algebraic trace functions in order to establish an asymptotic formula for a generalized cubic moment of modular L-functions at the central point s = 1/2 and for prime moduli q. As an application, we exploit our recent result on the mollification of the fourth moment of Dirichlet L-functions to derive that for any pair $(ω_1,ω_2)$ of multiplicative characters modulo q, there is a positive proportion of $χ$ (mod q) such that $L(χ, 1/2 ), L(χω_1, 1/2 )$ and $L(χω_2, 1/2)$ are simultaneously not too small.
