Sep 5: Max Fortier Bourque (Graduate Center of CUNY)
Moving one Riemann Surface Inside Another
In this talk, I will sketch a proof of the following parametric homotopy
principle: If two holomorphic embeddings between Riemann surfaces are
homotopic, then they are isotopic through holomorphic embeddings. The proof
uses a generalization of Teichmuller's theorem for quasiconformal
embeddings, the geometry of quadratic differentials, and Gardiner's
variational formula for extremal length.

Sep 12: Feng Luo (Rutgers University)
A Dilogarithm Identity on the Moduli Space of Curves
We establish an identity for closed hyperbolic surfaces whose
terms depend on the dilogarithms of the lengths of simple closed geodesics
in all 3holed spheres and 1holed tori in the surface. This is joint work
with Ser Peow Tan.

Sep 19: Yunhui Wu (Rice University)
Translation Lengths of Parabolic Isometries of CAT(0) Spaces and
its Application to the Geometry and Topology of Hadamard Manifolds
A CAT(0) space is a complete pathmetric space with a certain inequality property.
In this talk, we will discuss the translation length of parabolic isometries of CAT(0) spaces.
As an application, we will connect several open problems and conjectures on Hadamard
manifolds and moduli spaces of closed surfaces.
