Abstract
In the previous paper [Sun24], the author proved a uniform bound for sums of half-integral weight Kloosterman sums. This bound was applied to prove an exact formula for partitions of rank modulo 3. That uniform estimate provides a more precise bound for a certain class of multipliers compared to the 1983 result by Goldfeld and Sarnak and generalizes the 2009 result from Sarnak and Tsimerman to the half-integral weight case. However, the author only considered the case when the parameters satisfied . In this paper, we prove the same uniform bound when for further applications.
在上一篇论文[Sun24]中,作者证明了半积分权Kloosterman和和的一致界。这个界被用来证明秩模为3的分区的一个精确公式。与1983年Goldfeld和Sarnak的结果相比,该统一估计为某类乘数提供了更精确的界,并将2009年Sarnak和Tsimerman的结果推广到半积分权情况。然而,作者只考虑了参数满足m ~ n ~ <;0的情况。为了进一步的应用,我们证明了m ~ n ~ >;0时的一致界。
期刊介绍:
The Journal of Number Theory (JNT) features selected research articles that represent the broad spectrum of interest in contemporary number theory and allied areas. A valuable resource for mathematicians, the journal provides an international forum for the publication of original research in this field.
The Journal of Number Theory is encouraging submissions of quality, long articles where most or all of the technical details are included. The journal now considers and welcomes also papers in Computational Number Theory.
Starting in May 2019, JNT will have a new format with 3 sections:
JNT Prime targets (possibly very long with complete proofs) high impact papers. Articles published in this section will be granted 1 year promotional open access.
JNT General Section is for shorter papers. We particularly encourage submission from junior researchers. Every attempt will be made to expedite the review process for such submissions.
Computational JNT . This section aims to provide a forum to disseminate contributions which make significant use of computer calculations to derive novel number theoretic results. There will be an online repository where supplementary codes and data can be stored.
