本文将BG中关于素模的Kloosterman和的一些结果推广到一般模.这需要建立对应的加性集合$$ I^{-1}=\{x^{-1}:\quad x\in I\},$$其中$I$是剩余类环中模一个大正整数的区间。我们应用我们的边界上的多线性指数和Brun-Titchmarsh定理和估计非常短的Kloosterman和,从而推广我们以前的工作,设置一般模。
In the present paper, we generalize some of the results on Kloosterman sums proven in \cite{BG} for prime moduli to general moduli. This requires to establish the corresponding additive properties of the reciprocal set $$ I^{-1}=\{x^{-1}:\quad x\in I\}, $$ where $I$ is an interval in the ring of residue classes modulo a large positive integer. We apply our bounds on multilinear exponential sums to the Brun-Titchmarsh theorem and the estimate of very short Kloosterman sums, hence generalizing our earlier work to the setting of general modulus.
