中心点处Dirichlet $L$-函数的平均非零性

Average non-vanishing of Dirichlet $L$-functions at the central point

Kyle Pratt

AI总结:

该研究突破广义黎曼假设限制,通过对模q本原特征及区间内q双重平均,无条件证明至少50.073%的Dirichlet L函数中心点值非零,采用三段软化子的软化法,依赖Kloosterman和估计,同时指出存在可修正的错误。

摘要:

广义黎曼假设(GRH)表明,当$χ$取遍模$q$的本原特征时,至少50%的中心值$L\left(\frac{1}{2},χ\right)$是非零的。我们证明可以无条件地突破GRH的限制,即若对模$q$的本原特征取平均,同时对区间内的$q$取平均,则至少50.073%的中心值是非零的。证明采用带三段软化子的软化方法,依赖于Deshouillers与Iwaniec给出的Kloosterman和之和的估计。注:作者已注意到本工作存在一处错误。该错误似乎可通过不同论证修正,作者将适时发布更正。

英文摘要:

The Generalized Riemann Hypothesis implies that at least 50% of the central values $L \left( \frac{1}{2},χ\right)$ are non-vanishing as $χ$ ranges over primitive characters modulo $q$. We show that one may unconditionally go beyond GRH, in the sense that if one averages over primitive characters modulo $q$ and averages $q$ over an interval, then at least 50.073% of the central values are non-vanishing. The proof utilizes the mollification method with a three-piece mollifier, and relies on estimates for sums of Kloosterman sums due to Deshouillers and Iwaniec. Note: The author has been made aware of an error in this work. It seems the error can be fixed, by using a different argument, and the author will present a correction in due course.
