 PUBLIC VIVA-VOCE NOTIFICATION 2:00 pm, Lecture Hall 6 Hitchin pairs on a singular curve Pabitra Barik Chennai Mathematical Institute. 02-05-14 Abstract In this talk, we present the moduli problem of rank $2$ torsion free Hitchin pairs of fixed Euler characteristic $\chi$ on a reducible nodal curve. We describe the moduli space of the Hitchin pairs. We define the analogue of the classical Hitchin map and describe the geometry of general Hitchin fibre.
