二维Logistic映射的全局稳定性

Global stability for the 2-dimensional logistic map

János Dudás

摘要:

对于时滞逻辑斯谛方程$x_{n+1} = a x_n (a-x_{n-1})$,已知非平凡不动点对$1<a\leq 2$是局部稳定的,对$a>2$是不稳定的.我们证明了$1<a\leq 2$的不动点是全局稳定的,在这个意义上,它是局部稳定的,并吸引所有点的$S$,其中$S$包含那些$(x_0,x_1)\in \mathbb{R}_+^2$,序列$\left\lbrace x_n\right\rbrace \subset \mathbb{R}_+$。证明是分析和可靠的数值方法的组合。

英文摘要:

For the delayed logistic equation $x_{n+1} = a x_n (a-x_{n-1})$ it is well known that the nontrivial fixed point is locally stable for $1<a\leq 2$, and unstable for $a>2$. We prove that for $1<a\leq 2$ the fixed point is globally stable, in the sense that it is locally stable and attracts all points of $S$, where $S$ contains those $(x_0,x_1)\in \mathbb{R}_+^2$, for which the sequence $\left\lbrace x_n\right\rbrace \subset \mathbb{R}_+$. The proof is a combination of analytical and reliable numerical methods.
