Stochastic stability of Lyapunov exponents and Oseledets splittings for semi-Invertible Matrix cocycles
Communications on Pure and Applied Mathematics, 2015Co-Authors: Gary Froyland, Cecilia González-tokman, Anthony QuasAbstract:We establish (i) stability of Lyapunov exponents and (ii) convergence in probability of Oseledets spaces for semi-Invertible Matrix cocycles subjected to small random perturbations. The first part extends results of Ledrappier and Young to the semi-Invertible setting. The second part relies on the study of evolution of subspaces in the Grassmannian; the analysis developed here is based on higher-dimensional Mobius transformations and is likely to be of wider interest.
