As one of the primary speakers, HongKun was invited to give the opening talk in the conference on "SRB Measures for Non-Equilibrium Billiards." This expository talk both reviewed recent progress and indicated possible new directions and problems in chaotic systems. The more than 50 participants included experts in dynamical systems and probability theory from USA, Europe, Canada, and other places.
