Siegel metric and curvature of the moduli space of curves
Elisabetta Colombo, Paola Frediani
We study the curvature of the moduli space M_g of curves of genus g with the Siegel metric induced by the period map. We give an explicit formula for the holomorphic sectional curv…

Some results on the second Gaussian map for curves
Elisabetta Colombo, Paola Frediani
We study the second Gaussian map for a curve X of genus g, in relation with the second fundamental form of the period map. We exhibit a class of infinitely many curves with surject…
