One idealization of nonequilibrium statistical mechanics simply gives general smooth dynamics on a compact manifold, with new interpretations and new questions, which we shall review. In particular we shall introduce the natural physical (SRB) measure associated with a diffeomorphism f, and ask if it depends smoothly on f. We shall also introduce an analytic susceptibility function and study its singularities.
