Abstract:

Let T: XX be an Axiom A diffeomorphism, m the Gibbs state for a H\"older continuous function g. Assume  that f: X→ Rd is a H\"older
continuous function with ∫Xdm=0. If the components of f are cohomologously independent, then there exists a positive definite
symmetric matrix σ2:=σ2(f) such that Snf/n converges in distribution with respect to m to a Gaussian random variable with expectation 0 and covariance matrix σ2. Moreover, there exists a real number A>0 such that, for any integer n≥1, 

∏(m*{1/√n Snf ), N(0, σ2))≤A /√n,
where m* (1/√n Snf) denotes the distribution of 1/√n Snf with respect to m, and  ∏ is the Prokhorov metric.

Key words: multidimensional central limit theorem, Axiom A diffeomorphisms, symbolic dynamics, transfer operator
