On some differential-geometric aspects of the Torelli map
Published 17 Sep 2018 in math.AG and math.DG | (1809.06315v1)
Abstract: In this note we survey recent results on the extrinsic geometry of the Jacobian locus inside $\mathsf{A}_g$. We describe the second fundamental form of the Torelli map as a multiplication map, recall the relation between totally geodesic subvarieties and Hodge loci and survey various results related to totally geodesic subvarieties and the Jacobian locus.
