Decay of correlations in one and two dimensions
Authors:András Krámli
Institution:(1) József Attila University, 6720 Szeged, Hungary
Abstract:An exposition of some methods of proving exponential (stretched exponential) decay of correlations is given. One-dimensional strictly hyperbolic and quadratic maps and two-dimensional piecewise smooth, uniformly hyperbolic maps are considered. The emphasis is on the fundamental constructions of the Markov sieve method due to Bunimovich-Chernov-Sinai and those of Liverani's Hilbert metric method.
Keywords:Correlation decay  smooth and piecewise smooth hyperbolic maps  Markov sieve  cone of functions  Hilbert metric
