摘要:This talk contains three parts: (1) The existence of SRB measures and their properties for infinite dimensional dynamical systems and SRB measures for parabolic PDEs undergoing Hopf bifurcations driven by a periodic forcing with applications to the Brusselator; (2) Positive entropy implying the existence of horseshoes for infinite dimensional random dynamical systems; (3) Chaotic behavior of Anosov systems driven by an external forcing. This is based on the joint works with Wen Huang, Zeng Lian, Peidong Liu, Qiudong Wang and Lai-Sang Young.
