广义Fibonacci序列的算术性质

Arithmetic properties of generalized Fibonacci sequences

Soohyun Park

摘要:

广义Fibonacci序列是满足递归$f_n(s, t) = sf_{n - 1}(s, t) + tf_{n - 2}(s, t)$($s, t \in \mathbb{Z}$)的序列$\{f_n\}$,初始条件为$f_0(s, t) = 0$和$f_1(s, t) = 1$ .在最近的一篇论文中,Amdeberhan,Chen,Moll和Sagan考虑了广义Fibonacci序列的一些算术性质。具体来说,他们考虑了类似于$p$ -adic赋值和黎曼ζ函数的行为。在本文中,我们解决了他们提出的一些与这些主题有关的问题。我们还考虑了秩模$n$在更深入的和找到一个解释的秩在有限域的乘法群中的元素的顺序时,$n$是一个奇素数。最后,我们研究了当$t = -1$时,$s$的秩在不同值上的分布,并提出了进一步研究广义Fibonacci序列秩模素幂的方向。

英文摘要:

The generalized Fibonacci sequences are sequences $\{f_n\}$ which satisfy the recurrence $f_n(s, t) = sf_{n - 1}(s, t) + tf_{n - 2}(s, t)$ ($s, t \in \mathbb{Z}$) with initial conditions $f_0(s, t) = 0$ and $f_1(s, t) = 1$. In a recent paper, Amdeberhan, Chen, Moll, and Sagan considered some arithmetic properites of the generalized Fibonacci sequence. Specifically, they considered the behavior of analogues of the $p$-adic valuation and the Riemann zeta function. In this paper, we resolve some conjectures which they raised relating to these topics. We also consider the rank modulo $n$ in more depth and find an interpretation of the rank in terms of the order of an element in the multiplicative group of a finite field when $n$ is an odd prime. Finally, we study the distribution of the rank over different values of $s$ when $t = -1$ and suggest directions for further study involving the rank modulo prime powers of generalized Fibonacci sequences.
