In August I submitted my DPhil Thesis at the University of Oxford, under the supervision of Nigel Hitchin , where I looked at Higgs bundles for real forms by defining spectral data associated to them and studying these new objects. In particular, our construction gives directly the desingularization of the necessarily singular spectral curves associated to orthogonal Higgs bundles. The growth of snow crystals is dependent on the temperature and saturation of the environment. During the second lecture we construct Higgs bundles for real forms of classical complex Lie groups as fixed points of involutions, and describe the corresponding spectral data when known.

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.

In this work we constructed natural A,B,A -branes associated to anti-holomorphic involutions on compact Riemann surfaces. We study the real points through the associated spectral data and describe the topological invariants involved using KO, KR and equivariant K-theory. The first lecture introduces classical Higgs bundles and the Hitchin fibration, and describe the associated spectral data in the case of lajra Higgs bundles for classical complex Lie groups.
