Abstract
Every compact Riemann surface admits a natural projective structure as a consequence of the uniformization theorem. In this work we describe the construction of another natural projective structure on , namely the Hodge projective structure , related to the second fundamental form of the period map. We then describe how projective structures correspond to -differential forms on the moduli space of projective curves and, from this correspondence, we deduce that and are not the same structure.
