报告摘要:
In this talk, we will focus on the classical examples of partially hyperbolic diffeomorphisms in dimension three: Derived from Anosov diffeomorphisms, diffeomorphisms in neighborhoods of the time-one map of the geodesic flow on a surface of negative curvature, and skew products with circle fibers.For any of these classes, under the conservative assumption, we establish the following dichotomy: either the diffeomorphism is Anosov, or it possesses nonhyperbolic ergodic measures.
