报告简介:

In this talk, we consider the symbolic representation of systems driven by an invertible measurable mapping on a measurable space. We prove that when a system possesses an equicontinuous uniformly expanding subbundle, then it has a subsystem of its iterations randomly semi-conjugating to the full shift on two symbols. Examples such as random perturbation of partially hyperbolic systems, random composition of partially hyperbolic automorphisms on 3-d tori with a fixed central direction, and fiber partially hyperbolic maps on 3-d tori without stable subbundles are under consideration. This is a joint work with Wen Huang and Xue Liu.
