内容摘要:

Entropy and pressure are important invariants to measure complexity of dynamical systems. In this talk, we show that the intermediate entropy property holds true for a large class of vector fields--the star vector fields which includes the famous Lorenz attractor. On the other hand, considering the notion of pressure, the intermediate pressure property holds for Cr(r≥2) generic Lorenz attractors while it fails for Cr(r≥2) dense Lorenz attractors, which gives a sharp contrast.
