Example of a diffeomorphism for which the special ergodic theorem doesn't hold
Abstract
In this work we present an example of C∞-diffeomorphism of a compact 4-manifold such that it admits a global SRB measure μ but for which the special ergodic theorem doesn't hold. Namely, for this transformation there exist a continuous function φ and a positive constant α such that the following holds: the set of the initial points for which the Birkhoff time averages of the function φ differ from its μ--space average by at least α has zero Lebesgue measure but full Hausdorff dimension.
