报告题目:Measures of maximal u-entropy for maps that factor over Anosov
报告摘要:
We construct measures of maximal u-entropy for any partially hyperbolic diffeomorphism that factors over an Anosov torus automorphism and has mostly contracting center direction. The space of such measures has a finite dimension, and its extreme points are ergodic measures with pairwise disjoint supports. This is a joint work with Raul Ures, Marcelo Viana and Fan Yang.
