The metric theory of the pair correlation function of real-valued lacunary sequences

Niclas Technau, Zeév Rudnick

摘要:

设$\{ a(x) \}_{x=1}^{\infty}$为正的实值缺项序列。本文证明了几乎对每一个$α\in \mathbb{R}$,膨胀$αa(x)$的分数部分的成对相关函数都是泊松函数.通过使用调和分析,我们的结果-不管选择的实值序列$\{ a(x) \}_{x=1}^{\infty}$ -基本上可以减少到显示的解决方案的数量丢番图不等式$$ \vert n_1 (a(x_1)-a(y_1))- n_2(a(x_2)-a(y_2)) \vert < 1 $$在整数六元组$(n_1,n_2,x_1,x_2,y_1,y_2)$位于框$[-N,N]^6$与"排除对角线“,即$$x_1\neq y_1, \quad x_2 \neq y_2, \quad (n_1,n_2)\neq (0,0),$$是最多$N^{4-δ}$一些固定的$δ>0$,所有足够大的$N$。

英文摘要:

Let $\{ a(x) \}_{x=1}^{\infty}$ be a positive, real-valued, lacunary sequence. This note shows that the pair correlation function of the fractional parts of the dilations $αa(x)$ is Poissonian for Lebesgue almost every $α\in \mathbb{R}$. By using harmonic analysis, our result - irrespective of the choice of the real-valued sequence $\{ a(x) \}_{x=1}^{\infty}$ - can essentially be reduced to showing that the number of solutions to the Diophantine inequality $$ \vert n_1 (a(x_1)-a(y_1))- n_2(a(x_2)-a(y_2)) \vert < 1 $$ in integer six-tuples $(n_1,n_2,x_1,x_2,y_1,y_2)$ located in the box $[-N,N]^6$ with the ``excluded diagonals'', that is $$x_1\neq y_1, \quad x_2 \neq y_2, \quad (n_1,n_2)\neq (0,0),$$ is at most $N^{4-δ}$ for some fixed $δ>0$, for all sufficiently large $N$.
