熵的半连续性、平衡态的存在性和物理测度的连续性

Semicontinuity of entropy, existence of equilibrium states and continuity of physical measures

Vitor Araujo

摘要:

通过平衡态得到了物理测度的存在性和连续性的一些结果,并将这些结果应用于具有非平坦临界集的紧致流形上的非一致扩张变换,得到了物理测度连续性的充分条件,以及对于局部超同态,随机稳定性的充要条件.特别是,我们表明,在一定的条件下,随机鲁棒非一致膨胀意味着存在和连续变化的物理措施。

英文摘要:

We obtain some results of existence and continuity of physical measures through equilibrium states and apply these to non-uniformly expanding transformations on compact manifolds with non-flat critical sets, obtaining sufficient conditions for continuity of physical measures and, for local diffeomorphisms, necessary and sufficient conditions for stochastic stability. In particular we show that, under certain conditions, stochastically robust non-uniform expansion implies existence and continuous variation of physical measures.
