指数和多项式混合动力系统的Erdos-Renyi定律
Erdos-Renyi laws for exponentially and polynomially mixing dynamical systems
摘要:
Erdos-Renyi极限定律给出了一个时间窗的长度尺度,在这个尺度上,Birkhoff和的时间平均值有一个非平凡的几乎必然极限。我们建立了具有指数尾和多项式尾的Young Towers模型的动力系统上Holder观测量的Erdos-Renyi型极限律。这将早期的Erdos-Renyi极限定律的结果推广到具有一定程度双曲性的一类广泛的动力系统。
英文摘要:
Erdos-Renyi limit laws give the length scale of a time-window over which time-averages in Birkhoff sums have a non-trivial almost-sure limit. We establish Erdos-Renyi type limit laws for Holder observables on dynamical systems modeled by Young Towers with exponential and polynomial tails. This extends earlier results on Erdos-Renyi limit laws to a broad class of dynamical systems with some degree of hyperbolicity.
