On Higgs Bundles on Nodal Curves

This is a review article on some applications of generalised parabolic structures to the study of torsion free sheaves and L-twisted Hitchin pairs on nodal curves. In particular, we survey on the relation between representations of the fundamental group of a nodal curve and the moduli spaces of gene...

Sumario:This is a review article on some applications of generalised parabolic structures to the study of torsion free sheaves and L-twisted Hitchin pairs on nodal curves. In particular, we survey on the relation between representations of the fundamental group of a nodal curve and the moduli spaces of generalised parabolic bundles and generalised parabolic Ltwisted Hitchin pairs on its normalisation as well as on an analogue of the Hitchin map for generalised parabolic L-twisted Hitchin pairs.
