posted on 2017-11-22, 10:08 authored by Wael BahsounWael Bahsoun, Stefano Galatolo, Isaia Nisoli, Xiaolong NiuWe present a general setting in which the formula describing the linear response of the physical measure of a perturbed system can be obtained. In this general setting we obtain an algorithm to rigorously compute the linear
response. We apply our results to expanding circle maps. In particular, we present examples where we compute, up to a pre-specified error in the L1-norm, the response of expanding circle maps under stochastic and deterministic
perturbations. Moreover, we present an example where we compute, up to a
pre-specified error in the L1-norm, the response of the intermittent family at the boundary; i.e., when the unperturbed system is the doubling map.
