实多项式映射不变集的双曲性

Hyperbolicity of the invariant sets for the real polynomial maps

Xu Zhang

摘要:

众所周知,对于$a>4$,极大不变紧集上的Logistic映射$f_a(x)=ax(1-x)$的动力学行为是“简单的”,这可以用双曲动力系统和符号动力学理论清楚地解释.在一般的实多项式映射中是否也能观察到类似的现象?本文通过研究实多项式映射$f_a(x)=ag(x)$来研究这个问题,其中$a$是参数,$g$是一个实系数多项式,它至少有两个不同的实零点或只有一个实零点.

英文摘要:

It is well known that for $a>4$, the dynamical behaviors of the logistic map $f_a(x)=ax(1-x)$ on the maximal invariant compact set are "simple" which could be clearly explained by the theories of hyperbolic dynamics and symbolic dynamics. Is it possible that similar phenomena could be observed in general real polynomial maps? In this paper, we study this problem by investigating the real polynomial map $f_a(x)=ag(x)$, where $a$ is a parameter, and $g$ is a real-coefficient polynomial, which has at least two different real zeros or only one real zero.
