Disheng Xu 许地生

I am an assistant professor at Beijing International Center for Mathematical Research, Peking University, starting from August 2020. I obtained my Ph.D degree in October 2016 from Université Paris Diderot and Institut de mathématiques de Jussieu, under the supervision of Professor Artur Avila and Julie Déserti.

I had previously worked at Imperial College London (supervised by Davoud Cheraghi) , the University of Chicago (supervised by Prof. Amie Wilkinson) and KTH in Stockholm (supervised by Prof. Danijela Damjanovic).

Research Interests

  • Dynamical systems: Cocycles and associated Lyapunov exponents, rigidity phenomenon, partially hyperbolic systems, higher rank group actions, random dynamics, etc.

  • Spectral theory of Schrödinger operators.
