Birkhoff sums as distributions I: Regularity

Dynamical Systems 2024-12-16 v2 Analysis of PDEs

Abstract

We study Birkhoff sums as distributions. We obtain regularity results on such distributions for various dynamical systems with hyperbolicity, as hyperbolic linear maps on the torus and piecewise expanding maps on the interval. We also give some applications, as the study of advection in discrete dynamical systems.
