This is the homepage for the UT Geometry and String Theory Seminar.

Fall 2008 Schedule

This semester, we will cover several topics:

1. Superconformal Boundary Conditions for N=4 Super Yang-Mills, and the connections with 3D Mirror Symmetry
2. Kontsevich-Soibelman, Donaldson-Thomas Theory and Wall-Crossing Formulæ for N=2 Supersymmetric Gauge Theories
3. Developments in Rozansky-Witten Theory
