Abstract
The self-duality equations on a Riemann surface arise as dimensional reduction of self-dual Yang-Mills equations. Hitchin showed that the moduli space M of solutions of the self-duality equations on a compact Riemann surface of genus g > 1 has a hyper-Kähler structure. In particular M is a symplectic manifold. In this paper we elaborate on one of the symplectic structures, the details of which are missing in Hitchin's paper. Next we apply Quillen's determinant line bundle construction to show that M admits a prequantum line bundle. The Quillen curvature is shown to be proportional to the symplectic form mentioned above.
