关于某些数展开式的联合正规性

On the joint normality of certain digit expansions

Joseph Vandehey

摘要:

我们证明了一个点$x$是正规的关于遍历,数论变换$T$当且仅当$x$是正规的关于$T^n$的任何$n\ge 1$。这纠正了施魏格的一个错误证明。然后,使用一些见解Schweiger的原始证明,我们扩展这些结果,例如,显示一个数字是正常的,相对于经常连分数扩展当且仅当它是正常的,相对于奇连分数扩展。

英文摘要:

We prove that a point $x$ is normal with respect to an ergodic, number-theoretic transformation $T$ if and only if $x$ is normal with respect to $T^n$ for any $n\ge 1$. This corrects an erroneous proof of Schweiger. Then, using some insights from Schweiger's original proof, we extend these results, showing for example that a number is normal with respect to the regular continued fraction expansion if and only if it is normal with respect to the odd continued fraction expansion.
