查找具有给定数量的连续性的二进制字

Finding binary words with a given number of subsequences

Radosław Żak

摘要:

我们将具有给定连续数的二进制字与具有给定分母的有理数的连分数联系起来。我们推导出存在长度为$O(\log n \log \log n)$的二进制字符串具有完全的$n$连续性;在Zaremba猜想的假设下,这可以改进为$O(\log n)$。

英文摘要:

We relate binary words with a given number of subsequences to continued fractions of rational numbers with a given denominator. We deduce that there are binary strings of length $O(\log n \log \log n)$ with exactly $n$ subsequences; this can be improved to $O(\log n)$ under assumption of Zaremba's conjecture.
