報告摘要: In this talk, we study the space of ergodic measures of geometric Lorenz attractors. We show that Cr-generically (r≥2), periodic measures are dense and hence the ergodic measure space is path-connected, while Cr-densely, the singular measure is isolated in the ergodic measure space. Similar property holds for C1 singular hyperbolic attractors. We also explore the intermediate entropy property and finiteness of physical measures for star vector fields, in particular for singular hyperbolic attractors.
