复合模量的短character和

Short character sums for composite moduli

Mei-Chu Chang

摘要:

本文对具有小素因子的任意复合模建立了短特征标和的新估计。我们的主要结果改进了平方自由模的Graham-Ringrose界,也改进了Gallagher和Iwaniec的结果,当模$q$的核$q'=\prod_{p|q}p$满足$\log q'\sim \log q$时。指出了Dirichlet L-函数的零自由区域以及$\rm{P\acute{o}lya}$和Vinogradov不等式的一些应用.

英文摘要:

We establish new estimates on short character sums for arbitrary composite moduli with small prime factors. Our main result improves on the Graham-Ringrose bound for square free moduli and also on the result due to Gallagher and Iwaniec when the core $q'=\prod_{p|q}p$ of the modulus $q$ satisfies $\log q'\sim \log q$. Some applications to zero free regions of Dirichlet L-functions and the $\rm{P\acute{o}lya}$ and Vinogradov inequalities are indicated.
