再论中心流形的参数化方法

More on the parameterization method for center manifolds

Jan Bouwe van den Berg, Wouter Hetebrij, Bob Rink

摘要:

在前一篇文章中,我们推广了Cabré,Fontich和De la Llave的参数化方法到离散动力系统的中心流形。在本文中,我们将这个结果扩展到几个不同的设置。中心流形出现的自然背景是在含参数的动力系统中的分叉处。我们的第一个结果将表明,我们可以找到参数依赖的中心流形附近的歧点。此外,我们将参数化方法推广到常微分方程的不动点的中心流形。最后,我们将把我们的方法应用于一个反应扩散方程。在我们的应用中,我们将表明,自由获得共轭动力学的规范形式,使人们有可能获得详细的定性信息的中心动态。

英文摘要:

In a previous paper we generalized the parameterization method of Cabré, Fontich and De la Llave to center manifolds of discrete dynamical systems. In this paper, we extend this result to several different settings. The natural setting in which center manifolds occur is at bifurcations in dynamical systems with parameters. Our first results will show that we can find parameter-dependent center manifolds near bifurcation points. Furthermore, we will generalize the parameterization method to center manifolds of fixed points of ODEs. Finally, we will apply our method to a reaction diffusion equation. In our application, we will show that the freedom to obtain the conjugate dynamics in normal form makes it possible to obtain detailed qualitative information about the center dynamics.
