周期非自治Lyness递归的可积性与不可积性

Integrability and non-integrability of periodic non-autonomous Lyness recurrences

Anna Cima, Armengol Gasull, Víctor Mañosa

摘要:

本文研究了$x_{n+2}=(a_n+x_{n+1})/x_{n}$形式的非自治Lyness型递归,其中$\{a_n\}$是具有本原周期$k$的$k$ -周期正数序列.我们表明,对于$k\in\{1,2,3,6\}$的情况下,序列$\{x_n\}$的行为是简单的(可积),而对于其余的情况下,满足这种行为可以是复杂得多(混沌)。我们还表明,$k$是5的倍数的情况下,呈现出一些不同的功能。

英文摘要:

This paper studies non-autonomous Lyness type recurrences of the form $x_{n+2}=(a_n+x_{n+1})/x_{n}$, where $\{a_n\}$ is a $k$-periodic sequence of positive numbers with primitive period $k$. We show that for the cases $k\in\{1,2,3,6\}$ the behavior of the sequence $\{x_n\}$ is simple (integrable) while for the remaining cases satisfying this behavior can be much more complicated (chaotic). We also show that the cases where $k$ is a multiple of 5 present some different features.
