Uniqueness of the measure of maximal entropy for geodesic flows on surfaces

Yuri Lima, Davi Obata, Mauricio Poletti

We prove that if a geodesic flow on a closed orientable surface is transitive and has positive topological entropy, then it has a unique measure of maximal entropy. This…

Absolute continuity of stationary measures for random surface dynamics

Aaron Brown, Homin Lee, Davi Obata +1

We find conditions for stationary measures of random dynamical systems on surfaces having dissipative diffeomorphisms to be absolutely continuous. These conditions involve a unifor…

Simple Lyapunov spectrum of partially hyperbolic diffeomorphisms

Karina Marin, Davi Obata, Mauricio Poletti

We study the simplicity of the Lyapunov spectrum of partially hyperbolic diffeomorphisms. We prove that a class of volume-preserving partially hyperbolic diffeomorphisms is -a…

Absolute continuity of stationary measures

Aaron Brown, Homin Lee, Davi Obata +1

Let and be two volume preserving, Anosov diffeomorphisms on , sharing common stable and unstable cones. In this paper, we find conditions for the existence of…

Measures of maximal entropy for non-uniformly hyperbolic maps

Yuri Lima, Davi Obata, Mauricio Poletti

For maps, possibly non-invertible and with singularities, we prove that each homoclinic class of an ergodic adapted hyperbolic measure carries at most one adapted hyperbol…

Uniqueness of -Gibbs measures for hyperbolic skew products on

Sylvain Crovisier, Davi Obata, Mauricio Poletti

We study the -Gibbs measures of a certain class of uniformly hyperbolic skew products on . These systems have a strong unstable and a weak unstable directions. We…
