Law of Iterated Logarithm and Invariance Principle for One-parameter Families of Interval Maps
نویسنده
چکیده
We show that for almost every map in a transversal one-parameter family of piecewise expanding unimodal maps the Birkhoff sum of suitable observables along the forward orbit of the turning point satisfies the law of iterated logarithm. This result will follow from an almost sure invariance principle for the Birkhoff sum, as a function on the parameter space. Furthermore, we obtain a similar result for general one-parameter families of piecewise expanding maps on the interval.

Central Limit Theorems and Invariance Principles for Time-One Maps of Hyperbolic Flows
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 iter...

متن کاملThe Law of the Iterated Logarithm for Additive Functionals of Markov Chains
In the paper, the law of the iterated logarithm for additive functionals of Markov chains is obtained under some weak conditions, which are weaker than the conditions of invariance principle of additive functionals of Markov chains in M. Maxwell and M. Woodroofe [7] (2000). The main technique is the martingale argument and the theory of fractional coboundaries.
