Birkhoff recurrence theorem
WebWe bring into account a series of result in the infinite ergodic theory that we believe that they are relevant to the theory of non-extensive entropies. WebJan 1, 2014 · An interesting result known as Birkhoff’s ergodic theorem states that under certain conditions, the time average exists and is equal to the space average. The applications of ergodic theory are the main concern of this note. We will introduce fundamental concepts in ergodic theory, Birkhoff’s ergodic theorem and its …

WebAug 19, 2014 · Namely: Let T be a measure-preserving transformation of the probability space (X, B, m) and let f ∈ L1(m). We define the time mean of f at x to be lim n → ∞1 nn − 1 ∑ i = 0f(Ti(x)) if the limit exists. The phase or space mean of f is defined to be ∫Xf(x)dm. The ergodic theorem implies these means are equal a.e. for all f ∈ L1(m ...

WebTheorem A, with property (v′ ) below added to the conclusions, extends the main theorem from the paper [PZ], where the density of periodic orbits in Fr Ω was proved. The idea of the proof, as in [PZ], is to apply Pesin and Katok theories; see [HK, Suplement] for a general theory and [PU, Ch. 9] for its adaptation in holomorphic iteration.
