实直线上的随机动力系统

Random dynamical systems on a real line

Anna Gordenko

摘要:

我们研究实数线上的随机动力系统,考虑每一个动力系统以及由逆映射生成的动力系统。我们发现,有这样的系统的正向和反向行为之间的二元性,将它们分成四类(在动态和静态措施方面)。这类似于已知的[0,1]上的光滑动力学的结果,建立在端点处的李雅普诺夫指数方面;然而,我们的论点是纯粹的拓扑,因此我们的结果适用于实直线同胚的一般情况。

英文摘要:

We study random dynamical systems on the real line, considering each dynamical system together with the one generated by the inverse maps. We show that there is a duality between forward and inverse behaviour for such systems, splitting them into four classes (in terms of both dynamical and stationary measure aspects). This is analogous to the results already known for the smooth dynamics on [0,1], established in terms of the Lyapunov exponents at the endpoints; however, our arguments are purely topological, and thus our result is applicable to the general case of homeomorphisms of the real line.
