Local large deviations for periodic infinite horizon Lorentz gases

Abstract

We prove local large deviations for the periodic infinite horizon Lorentz gas viewed as a ${\mathbb{Z}}^d$-cover ($d=1,2$) of a dispersing billiard. In addition to this specific example, we prove a general result for a class of nonuniformly hyperbolic dynamical systems and observables associated with central limit theorems with nonstandard normalisation.
