Real structures on moduli spaces of Higgs bundles
David Baraglia, Laura P. Schaposnik
We construct triples of commuting real structures on the moduli space of Higgs bundles, whose fixed loci are branes of type (B, A, A), (A, B, A) and (A, A, B). We study the real po…
Spectral data for U(m,m)-Higgs bundles
Laura P. Schaposnik
We define and study spectral data associated to U(m,m)-Higgs bundles through the Hitchin fibration. We give a new interpretation of the topological invariants involved, as well as…
Nonabelianization of Higgs bundles
Nigel Hitchin, Laura P. Schaposnik
The character varieties of representations of a surface group into the Lie groups SL(m,H), SO(2m,H) and Sp(m,m) have a holomorphic description in terms of the moduli space of Higgs…
Spectral data for G-Higgs bundles
Laura P. Schaposnik
We develop a new geometric method of understanding principal G-Higgs bundles through their spectral data, for G a real form of a complex Lie group. In particular, we consider the c…
