Groups and Dynamics: Lyapunov spectral stability and collapse for random composition of Blaschke Products by Anthony Quas (University of Victoria)
We consider random dynamical systems where at each stage one applies a Blaschke product. Motivated by questions on mixing of invariant measures on the unit circle, we study the composition of the associated Perron-Frobenius operators, acting on a Hardy space. We describe the complete Lyapunov spectrum, and address questions of stability of the spectrum under perturbations to the operator cocycle. Submitted by
