一类双曲集保持动力学的约束

Constraints On Dynamics Preserving Certain Hyperbolic Sets

Aaron W. Brown

摘要:

我们建立了两个结果下,双曲集的拓扑约束环境动力学。首先,如果一个集合对于某个双同态是一个紧的、传递的、扩张的余维为1的双曲吸引子,那么它对于任何双同态是一个传递的、扩张的余维为1的吸引子(或收缩的排斥子)的并集,使得它是双曲的。其次,如果一个集合对于一个曲面双同态是一个非游荡的、局部极大的、紧的双曲集,那么对于任何它是双曲的双同态,它都是局部极大的。

英文摘要:

We establish two results under which the topology of a hyperbolic set constrains ambient dynamics. First if a set is a compact, transitive, expanding hyperbolic attractor of codimension 1 for some diffeomorphism, then it is a union of transitive, expanding attractors (or contracting repellers) of codimension 1 for any diffeomorphism such that it is hyperbolic. Secondly, if a set is a nonwandering, locally maximal, compact hyperbolic set for a surface diffeomorphism, then it is locally maximal for any diffeomorphism for which it is hyperbolic.
