Multifractal analysis of geodesic flows on surfaces without focal points
Kiho Park, Tianyu Wang
We study multifractal spectra of the geodesic flows on rank 1 surfaces without focal points. We compute the entropy of the level sets for the Lyapunov exponents and estimate its Ha…

Unique equilibrium states, large deviations and Lyapunov spectra for the Katok Map
Tianyu Wang
We study the thermodynamic formalism of a non-uniformly hyperbolic diffeomorphism on the 2-torus, known as the Katok map. We prove for a Hölder continuous potential wi…
