About the seminar series:

As part of a collaborative project with Iran funded by the NNSFC we will have seminar talks (BeST for Beijing-Shenzhen-Tehran) which we expect to have a monthly frequency.  This project involves SUSTech and PKU researchers from the Chinese side.


Let f be an irreducible non-invertible Anosov maps on d-torus. If the stable bundle is one dimensional, we show that f has integrable unstable bundle, if and only if, every periodic point of f admits the same stable Lyapunov exponents. For higher dimensional stable bundle, we prove the same result for perturbations of non-invertible linear Anosov maps with real simple spectrum.
