LAURA SCHAPOSNIK THESIS

After hearing a lot on Langlands duality and branes in the moduli space of Higgs bundles here , I started looking at what different A,B,A and B,A,A branes could be constructed in the moduli spaces of principal Higgs bundles. Here we investigate this situation, which corresponds to the coalescence of D-branes in physics terminology, including the case of Sp m,m -Higgs bundles studied in arXiv: Steven Bradlow Post-doc reference. Mathematische Arbeitstagung, Bonn, Germany. Monodromy of SL 2 -Hitchin Systems. Here is my CV.

Here are my publications. In the case of certain real forms, the corresponding moduli space of Higgs bundles is closely related to the moduli space of rank 2 semistable vector bundles or parabolic bundles on an algebraic curve. These branes are closely related to representations of the surface which extend to the 3-manifold and we are currently studying this relation and its implications.

Through combinatorial methods, I could obtain an explicit description of the monodromy action on the mod 2 cohomology for SL 2,C Higgs bundles, and by understanding the orbits, obtain information about the connected components of the moduli space of real SL 2,R Higgs bundles.
