随机稳定吸引子

Infinitely Many Stochastically Stable Attractors

Vitor Araujo

摘要:

设f是紧致有限维无边界流形M的一个非纯映射,它具有无穷多个共存吸引子.假设每个吸引子支持一个随机稳定的概率测度,并且每个吸引子的吸引盆的并集几乎覆盖M的所有Lebesgue点。我们证明了在随机扰动下几乎所有轨道的时间平均都是由有限个概率测度给出的。此外,当扰动接近原始映射f时,这些概率测度接近吸引子支持的概率测度。

英文摘要:

Let f be a diffeomorphism of a compact finite dimensional boundaryless manifold M exhibiting infinitely many coexisting attractors. Assume that each attractor supports a stochastically stable probability measure and that the union of the basins of attraction of each attractor covers Lebesgue almost all points of M. We prove that the time averages of almost all orbits under random perturbations are given by a finite number of probability measures. Moreover these probability measures are close to the probability measures supported by the attractors when the perturbations are close to the original map f.
