最小间隔的度量理论

数论 2018-05-30 v2

摘要

我们研究形如Aα={αa(n)}\mathcal A^\alpha = \{\alpha a(n)\}的序列的小数部分的最小间隔统计量,其中A={a(n)}\mathcal A = \{a(n)\}是一个互异整数序列。假设该序列的加性能量接近其最小可能值,我们证明对于几乎所有的α\alpha,最小间隔δminα(N)=min{αa(m)αa(n)mod1:1mnN}\delta_{\min}^\alpha(N)=\min\{\alpha a(m)-\alpha a(n)\bmod 1: 1\leq m\neq n\leq N\}接近于随机序列的最小间隔。
