$\mathbb{Q}$ -Bonacci单词和数字

$\mathbb{Q}$-bonacci words and numbers

Sergey Kirgizov

摘要:

我们提出了一个相当奇怪的推广多步斐波那契数。对于任何正有理数$q$,我们枚举长度为$n$的二进制字,其形式为$0^a1^b$的最大因子满足$a = 0$或$aq > b$。当$q$是整数时,我们重新发现了经典的多步斐波那契数:Fibonacci,Tribonacci,Tetranacci等。当$q$不是整数时,得到的递归关系与某些限制整数组合有关。我们还讨论了这些话的格雷码,和一个可能新颖的黄金分割率的推广。

英文摘要:

We present a quite curious generalization of multi-step Fibonacci numbers. For any positive rational $q$, we enumerate binary words of length $n$ whose maximal factors of the form $0^a1^b$ satisfy $a = 0$ or $aq > b$. When $q$ is an integer we rediscover classical multi-step Fibonacci numbers: Fibonacci, Tribonacci, Tetranacci, etc. When $q$ is not an integer, obtained recurrence relations are connected to certain restricted integer compositions. We also discuss Gray codes for these words, and a possibly novel generalization of the golden ratio.
