与β-变换有关的一致丢番图逼近

Uniform Diophantine approximation related to beta-transformations

Wanlou Wu

摘要:

对于任何$β>1$,设$T_β$是经典的$β$ -变换。固定$x_0\in[0,1]$和一个非负实数$\hat{v}$,我们计算实数集$x\in[0,1]$的Hausdorff维数,并证明了对于每个足够大的整数$N$,存在一个整数$n$,其中$1\leq n\leq N$使得$T_β^nx$和$x_0$之间的距离至多等于$β^{-N\hat{v}}$。本文将Bugeaud和Liao \cite{YLiao2016}的结果推广到单位区间内的所有点$x_0$。

英文摘要:

For any $β>1$, let $T_β$ be the classical $β$-transformations. Fix $x_0\in[0,1]$ and a nonnegative real number $\hat{v}$, we compute the Hausdorff dimension of the set of real numbers $x\in[0,1]$ with the property that, for every sufficiently large integer $N$, there is an integer $n$ with $1\leq n\leq N$ such that the distance between $T_β^nx$ and $x_0$ is at most equal to $β^{-N\hat{v}}$. This work extends the result of Bugeaud and Liao \cite{YLiao2016} to every point $x_0$ in unit interval.
