黎曼ζ函数高阶导数的零点

Zeros of higher derivatives of Riemann zeta function

Mithun Kumar Das, Sudhir Pujahari

AI总结:

该研究将Conrey关于黎曼ζ函数的结果推广到高阶导数的更短区间,通过优化短区间内的mollifier长度改进了零点密度估计的经典误差项,并证明Matsumoto-Tanigawa的$η_k$-函数几乎所有非平凡零点聚集在临界线附近。

摘要:

本文将Conrey的结果[5,定理2]推广到ζ函数高阶导数的更短区间情形,即研究短区间内ζ函数的两个有限阶导数的乘积与一个mollifier(光滑化子)相乘后的均值。研究过程中,我们在部分短区间内得到了比Conrey结果所隐含的mollifier长度更优的mollifier长度。这些更精细的研究让我们得以改进Levinson和Montgomery[13]、Ki和Lee[11]关于$ζ^{(k)}$零点密度估计的若干经典结果的误差项。此外,我们证明了Matsumoto-Tanigawa的$η_k$-函数的几乎所有非平凡零点都聚集在临界线附近。

英文摘要:

In this article, we extend the result of Conrey [5, Theorem 2] to shorter intervals for higher-order derivatives of the zeta function. That is we study the mean value of the product of two finite order derivatives of the zeta function multiplied by a mollifier in short intervals. In this process, we obtain better mollifier length in some short intervals compared to the length of mollifier implied by Conrey's result. These finer studies allow us to refine the error term of some classical results of Levinson and Montgomery [13], Ki and Lee [11] on zero density estimates of $ζ^{(k)}$. Further, we showed that almost all non-trivial zeros of Matsumoto-Tanigawa's $η_k$-function cluster near the critical line.
