Topological stability of hyperbolic sets of flows under random perturbations
Qiuxia Liu Peidong Liu
In this paper we consider $C^{0}$ random perturbations of a hyperbolic set of a flow. We show that the hyperbolic set is structurally semi-stable under such perturbations.

A note on partially hyperbolic attractors: Entropy conjecture and SRB measures
Peidong Liu Kening Lu
In this note we show that, for a class of partially hyperbolic $C^r$ ($r \geq 1$) diffeomorphisms, (1) Shub's entropy conjecture holds true; (2) SRB measures exist as zero-noise limits.

Existence of SRB measures for a class of partially hyperbolic attractors in banach spaces
Zeng Lian Peidong Liu Kening Lu

In this paper, we study the existence of SRB measures for infinite dimensional dynamical systems in a Banach space. We show that if the system has a partially hyperbolic attractor with nontrivial finite dimensional unstable directions, then it has an SRB measure.
