关于一个幂和问题的解

On the solutions to a power sum problem

Johan Andersson

摘要:

在最近的一篇论文中,我们证明了,如果(*)= \inf_{|z_k|=1} \max_{v=1,...,n^2-n}| \sum_{k=1}^n z_k^v|,则(*)= \sqrt{n-1}如果n-1是素数幂。我们证明了Fabrykowski的一个构造给出了极小系统(z_1,...,Z_n)这个问题。该构造依赖于n-1阶完全差集的存在性。作为一个开放的问题,我们问是否所有的解决方案将产生于这个建设。在本文中,我们证明了这是正确的,事实上,如果不存在n-1阶的完美差集(根据素幂猜想,如果n-1不是素幂,则该差集为真),那么我们就有严格不等式(*)> \sqrt{n-1}。

英文摘要:

In a recent paper we proved that if (*)=\inf_{|z_k|=1}\max_{v=1,...,n^2-n} |\sum_{k=1}^n z_k^v|, then (*)=\sqrt{n-1} if n-1 is a prime power. We proved that a construction of Fabrykowski gives minimal systems (z_1,...,z_n) to this problem. The construction depends on the existence of perfect difference sets of order n-1. As an open problem we asked whether all solutions would arise from this construction. In this paper we show that this is true and in fact if there exist no perfect difference set of order n-1 (which by the prime power conjecture is true if n-1 is not a prime power), then we have the strict inequality (*)>\sqrt{n-1}.
