Abstract/Media

Let S be a surface of genus g with n punctures.  Assume 3g-3+n is at least 2.  Let T(S) be the Teichmuller space of S with the Teichmuller metric. The purpose of this talk is to discuss the result that T(S) is quasi-isometrically rigid. I will discuss some background to this result and a few ideas that go into the proof including the notion of coarse differentiation.   This is joint work with Alex Eskin and Kasra Rafi.
