If n (c;r) has a derivation in g that is not in g 0, then its must have one which is combination of such, acting on v as X 1 + X 2 + . This forces all the g kig 1 k to be the same and all the c i to be the same. The reciprocal is clear. In particular, all algebras n (c;r) with c 1 = :::= c ...

WebVandaag · 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 ...
