New Kahler metrics on Teichmuller space and harmonic maps

We survey several known facts on Teichmuller space and present a new way of constructing Kahler metrics on Teichmuller space via harmonic map techniques. This is a joint work with Wan and Zhang.

Hyperbolic dynamics in the rigidity of group actions

We will survey the use of hyperbolic dynamics in the rigidity of group actions on manifolds. We will focus on higher rank free abelian group or higher rank lattice actions that have some uniform hyperbolicity such as Anosov diffeomorphism or flow. We will discuss old and new results with some ideas of the proof if time permits.
