Real slices of the moduli space of Higgs bundlesQMAP Seminar
|Speaker: ||Laura Schaposnik, University of Illinois at Urbana Champaign|

Through the hyperkähler structure of the moduli space of
Higgs bundles for complex groups we shall construct three natural
involutions whose fixed points in the moduli space give branes in the
A-model and B-model with respect to each of the complex structures.
Then, by means of spectral data, we shall look at these branes and
their topological invariants, and propose what the dual branes should
be under Langlands duality.
