Abstract

Linear response means that the equilibrium measures of chaotic dynamical systems react to perturbations linearly in the perturbation strength. After reviewing some obstructions to linear response for 1D expanding maps, I will present some results on linear response for discontinuous perturbations and systems with holes in higher dimensions.
