报告摘要 Abstract: 
We present the results of N. Zarate and S. Romaña about the rigidity of Lyapunov exponents of Anosov geodesic flows. The main result to be presented is the following: under a strong assumption on Lyapunov exponents, the geodesic flow must be of a given type. We will introduce the problem, pointing out the main issues and ideas that appear in the proof.
