列文二进制正规数的偏差确切阶

数论 2022-08-26 v3

摘要

莫德哈伊·列文构造了一个在二进制下正规的数 α\alpha,并且序列 {2nα}n=0,1,2,\left\{2^n \alpha\right\}_{n=0,1,2,\ldots} 具有非常小的偏差 DND_N。事实上我们有 NDN=O((logN)2)N\cdot D_N = \mathcal{O} \left(\left(\log N\right)^2\right)。这意味着 α\alpha 是极高质量的正规数。在本文中我们证明该估计是最佳可能的,即对无穷多个 NNNDNc(logN)2N\cdot D_N \geq c \cdot \left(\log N\right)^2
