On distributional limit laws for recurrence
arxiv(2024)
摘要
For a probability measure preserving dynamical system (𝒳,f,μ),
the Poincaré Recurrence Theorem asserts that μ-almost every orbit is
recurrent with respect to its initial condition. This motivates study of the
statistics of the process X_n(x)=dist(f^n(x),x)), and real-valued
functions thereof. For a wide class of non-uniformly expanding dynamical
systems, we show that the time-n counting process R_n(x) associated to the
number recurrences below a certain radii sequence r_n(τ) follows an
averaged Poisson distribution G(τ). Furthermore, we obtain
quantitative results on almost sure rates for the recurrence statistics of the
process X_n.
