Title: On branes in the moduli space of Higgs bundles
Speaker: Laura Schaposnik
Speaker Info: UIC
Brief Description:
Special Note:

The moduli space of Higgs bundles, as introduced by Hitchin in 1987, carries a natural Hyperkhaler structure through which one may consider A-branes (Lagrangian subspaces) and B-branes (holomorphic subspaces). During this talk, we shall first introduce Higgs bundles and the associated Hitchin fibration, and then describe different methods through which interesting branes may be constructed. Finally, we shall consider the geometry of these branes, and their relation to 3-manifolds, representation theory, and the geometric Langlands program.
