关于二次数域中$αp$模一的分布

On the distribution of $αp$ modulo one in quadratic number fields

Stephan Baier, Dwaipayan Mazumder, Marc Technau

AI总结:

该研究将类数1的二次数域中素元对应的$αp$模一分布的相关指数从$1/4$改进至$7/22$,推广了Harman在$\boldsymbol{\text{Q}}(i)$上的结果,核心方法是扩展筛法并借助带Größen特征的Hecke L-函数解析性质估计光滑和。

摘要:

我们研究类数为1的二次数域$\boldsymbol{\text{K}}$中$αp$模一的分布,其中$p$限定为$\boldsymbol{\text{K}}$的整数环中的素元。本文将第一、第三作者针对虚二次数域\textit{(文献[BT])}以及第一、第二作者针对实二次数域\textit{(文献[BM])}得到的相关指数$1/4$改进为$7/22$。这推广了Harman的结果\textit{(文献[HarZi])},后者通过扩展其针对$\boldsymbol{\text{Q}}$得到该指数的方法\textit{(文献[harman1996on-the-distribu])},对$\boldsymbol{\text{Q}}(i)$得到了相同的$7/22$指数。我们的证明基于将他的筛法推广到任意数域。此外,我们需要对文献[BM]中出现的、素理想上的某些光滑和进行渐近估计,为此我们使用了带Größen特征的Hecke L-函数的解析性质。

英文摘要:

We investigate the distribution of $αp$ modulo one in quadratic number fields $\mathbb{K}$ with class number one, where $p$ is restricted to prime elements in the ring of integers of $\mathbb{K}$. Here we improve the relevant exponent $1/4$ obtained by the first and third named authors for imaginary quadratic number fields \cite{BT} and by the first and second named authors for real quadratic number fields \cite{BM} to $7/22$. This generalizes a result of Harman \cite{HarZi} who obtained the same exponent $7/22$ for $\mathbb{Q}(i)$ by extending his method which gave this exponent for $\mathbb{Q}$ \cite{harman1996on-the-distribu}. Our proof is based on an extension of his sieve method to arbitrary number fields. Moreover, we need an asymptotic evaluation of certain smooth sums over prime ideals appearing in \cite{BM}, for which we use analytic properties of Hecke L-functions with Größencharacters.
