Central Limit Theorems and Invariance Principles for Time-One Maps of Hyperbolic Flows
نویسندگان
چکیده
We give a general method for deducing statistical limit laws in situations where rapid decay of correlations has been established. As an application of this method, we obtain new results for time-one maps of hyperbolic flows. In particular, using recent results of Dolgopyat, we prove that many classical limit theorems of probability theory, such as the central limit theorem, the law of the iterated logarithm, and approximation by Brownian motion (almost sure invariance principle), are typically valid for such time-one maps. The central limit theorem for hyperbolic flows goes back to Ratner 1973 and is always valid, irrespective of mixing hypotheses.

Statistical Limit Theorems for Suspension Flows
In dynamical systems theory, a standard method for passing from discrete time to continuous time is to construct the suspension flow under a roof function. In this paper, we give conditions under which statistical laws, such as the central limit theorem and almost sure invariance principle, for the underlying discrete time system are inherited by the suspension flow. As a consequence, we give a...
متن کاملCentral Limit Theorems for Non-invertible Measure Preserving Maps
This paper is motivated by the question “How can we produce the characteristics of a Wiener process (Brownian motion) from a semi-dynamical system?”. This question is intimately connected with Central Limit Theorems for non-invertible maps and various invariance principles. Many results on CLT and invariance principles for maps have been proved, see e.g. the surveys Denker [4] and Mackey and Ty...
متن کاملAlmost Sure Invariance Principle for Nonuniformly Hyperbolic Systems
We prove an almost sure invariance principle that is valid for general classes of nonuniformly expanding and nonuniformly hyperbolic dynamical systems. Discrete time systems and flows are covered by this result. In particular, the result applies to the planar periodic Lorentz flow with finite horizon. Statistical limit laws such as the central limit theorem, the law of the iterated logarithm, a...
متن کاملStatistical Properties of Endomorphisms and Compact Group Extensions
The statistical properties of endomorphisms under the assumption that the associated Perron– Frobenius operator is quasicompact are considered. In particular, the central limit theorem, weak invariance principle and law of the iterated logarithm for sufficiently regular observations are examined. The approach clarifies the role of the usual assumptions of ergodicity, weak mixing, and exactness....
متن کاملInvariance principles for fractionally integrated nonlinear processes
Invariance principles (or functional central limit theorems) play an important role in econometrics and statistics. For example, to obtain asymptotic distributions of unit-root test statistics, researchers have applied invariance principles of various forms; see [24, 30, 40] among others. The primary goal of this paper is to establish invariance principles for a class of fractionally integrated...
