C0动力学的类SRB测度

SRB-like measures for C0 dynamics

Eleonora Catsigeras, Heber Enrich

摘要:

对于紧致流形M上的任何连续映射f,我们将SRB类(或可观测)概率定义为Sinai-Ruelle-Bowen(即物理)测度的推广。我们证明了f有可观察的措施,即使SRB措施不存在。我们证明了,如果研究者的目的是描述Lebesgue的渐近统计量几乎每一个初态的可观测性的定义是最佳的。确切地说,所有可观测测度的永不空集O是M中Borel概率的最小弱 *-紧集,它包含M中勒贝格几乎所有x的经验概率的所有收敛连续性的极限(在弱 * 拓扑中)。我们证明了O中的任何孤立测度都是SRB。最后,我们得出结论:如果O是有限的或可数无限的,则存在(至多可数个)SRB测度,使得它们的盆的并覆盖M Lebesgue a.e.

英文摘要:

For any continuous map f on a compact manifold M, we define the SRB-like (or observable) probabilities as a generalization of Sinai-Ruelle-Bowen (i.e. physical) measures. We prove that f has observable measures, even if SRB measures do not exist. We prove that the definition of observability is optimal, provided that the purpose of the researcher is to describe the asymptotic statistics for Lebesgue almost every initial state. Precisely, the never empty set O of all the observable measures, is the minimal weak*-compact set of Borel probabilities in M that contains the limits (in the weak* topology) of all the convergent subsequences of the empiric probabilities for Lebesgue almost all x in M. We prove that any isolated measure in O is SRB. Finally we conclude that if O is finite or countable infinite, then there exist (up to countable many) SRB measures such that the union of their basins cover M Lebesgue a.e.
