The Entropy Conjecture for Diffeomorphisms away from Tangencies
Liao Gang, Marcelo Viana, Jiagang Yang
We prove that every C1 diffeomorphism away from homoclinic tangencies is entropy expansive, with locally uniform expansivity constant. Consequently, such diffeomorphisms satisfy Sh…

Physical Measure and Absolute Continuity for One-Dimensional Center Direction
Marcelo Viana, Jiagang Yang
For a class of partially hyperbolic , diffeomorphisms with circle center leaves we prove existence and finiteness of physical (or Sinai-Ruelle-Bowen) measures, whose bas…

Some results on perturbations to Lyapunov exponents
Chao Liang, Wenxiang Sun, Jiagang Yang
In this paper, we study two properties of the Lyapunov exponents under small perturbations: one is when we can remove zero Lyapunov exponents and the other is when we can distingui…
