Physical-Space Scarring in Generic Bunimovich Stadia

Heng Li, Xizhi Liu

For the family of Dirichlet stadia $S_{t}$ whose rectangular part has height $I ¨ $ and half-length $I ¨ t /2$ , $t \in [1, 2]$ , we show that for Lebesgue almost every $t$ there exist real…

Entropy Continuity of Lyapunov Exponents for Non-flat 1-dimensional Maps

Hengyi Li

We show that the continuity property of Lyapunov exponents proved in \cite{BCS-Exponents} for smooth surface diffeomorphisms extends to smooth interval maps, in the case when the m…

Continuity of Lyapunov exponents for C^r one-dimensional maps

Alexandre Delplanque, Hengyi Li

We prove the entropic continuity of Lyapunov exponent for C^r maps of the interval or of the circle with large entropy for r>1, without making any assumptions on the set of critica…
