Abstract
The twistor space of the moduli space of solutions of Hitchin’s self-duality equations can be identified with the Deligne-Hitchin moduli space of λ-connections. We use real projective structures on Riemann surfaces to prove the existence of new components of real holomorphic sections of the Deligne-Hitchin moduli space. Applying the twistorial construction we show the existence of new hyper-Kähler manifolds associated to any compact Riemann surface of genus g≥ 2. These hyper-Kähler manifolds can be considered as moduli spaces of (certain) singular solutions of the self-duality equations.

AU - Heller, Sebastian
N1 - Funding Information: The author thanks Jörg Teschner for first pointing us to (integral) grafting of Fuchsian projective structures, and its interpretation as constant curvature -1 metrics with singularities on compact Riemann surfaces. The authors thanks the referees for helpful comments. The author also thanks the DFG for financial support through the research training group RTG 1670.
