Description
I will show a simple example of fast-slow partially hyperbolic systems in which the fast variable acts similarly to a Gaussian  noise and will obtain, for such a deterministic setting, results similar to the one obtained in Freidlin--Wentzell theory. In particular, I will show conditions under which there exists a unique SRB measure with exponential decay of correlations.
