作为分布的Birkhoff和II:在动力系统变形中的应用

Birkhoff sums as distributions II: Applications to deformations of dynamical systems

Clodoaldo Grotta-Ragazzo, Daniel Smania

摘要:

通常一维动力系统的拓扑类是有限余维光滑流形。我们描述了一种方法来证明这种说法,我们相信可以应用在许多设置。在这项工作中,我们将实现它的分段扩展地图。最重要的一步将是识别的无穷小变形与原始的伯克霍夫和(最多添加一个Lipschitz函数),这使我们能够使用遍历性质的分段扩展映射来研究无穷小变形的规律性。

英文摘要:

Often topological classes of one-dimensional dynamical systems are finite codimension smooth manifolds. We describe a method to prove this sort of statement that we believe can be applied in many settings. In this work we will implement it for piecewise expanding maps. The most important step will be the identification of infinitesimal deformations with primitives of Birkhoff sums (up to addition of a Lipschitz function), that allows us to use the ergodic properties of piecewise expanding maps to study the regularity of infinitesimal deformations.
