二次Dirichlet L函数低零点的n层密度

The n-level densities of low-lying zeros of quadratic Dirichlet L-functions

Jake Levinson, Steven J. Miller

摘要:

Rubinstein和Gao以前的工作计算了检验函数的二次Dirichlet L函数族的n层密度,其中傅里叶变换的支撑之和至多为2,并且在n < 4的范围内与随机矩阵理论的预测一致,但仅在有限的范围内。我们推广了这些结果,并在n < 8时显示出一致性,并将更高的n简化为一个傅里叶变换恒等式。证明涉及到采用一种新的组合视角,将所有项转换为规范形式,这有利于双方的比较。

英文摘要:

Previous work by Rubinstein and Gao computed the n-level densities for families of quadratic Dirichlet L-functions for test functions where the sum of the supports of the Fourier transforms is at most 2, and showed agreement with random matrix theory predictions in this range for n < 4 but only in a restricted range for larger n. We extend these results and show agreement for n < 8, and reduce higher n to a Fourier transform identity. The proof involves adopting a new combinatorial perspective to convert all terms to a canonical form, which facilitates the comparison of the two sides.
