WebHoje · Abstract. We are interested in studying the variation of the Hitchin fibration in moduli spaces of parabolic Higgs bundles, under the action of a ramified covering. Given a degree two map π: Y → X between compact Riemann surfaces, we may pull back a Higgs bundle from X to Y, the lifted Higgs bundle tends to have many apparent singularities ... WebThe study of Higgs bundles on curves has been initiated by Hitchin [ 28] in relation to the construction of solutions to a dimensional reduction of the Yang–Mills equation. An essential device to study Higgs bundles has been the Hitchin map, which associates to a pair ( E, θ ), the characteristic polynomial of the Higgs field θ.
