Stochastic stability of Pollicott-Ruelle resonances (1407.8531v2)
Published 31 Jul 2014 in math.DS, math.AP, and math.SP
Abstract: Pollicott-Ruelle resonances for chaotic flows are the characteristic frequencies of correlations. They are typically defined as eigenvalues of the generator of the flow acting on specially designed functional spaces. We show that these resonances can be computed as viscosity limits of eigenvalues of second order elliptic operators. These eigenvalues are the characteristic frequencies of correlations for a stochastically perturbed flow.
