DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Wagon/5/">Sc
 hiffer variations of hypersurfaces and the generic Torelli theorem</a>\nby
  Claire Voisin (Collège de France) as part of Western Algebraic Geometry 
 ONline\n\n\nAbstract\nThe generic Torelli theorem for hypersurfaces of deg
 ree d and dimension n-1 was proved by Donagi in the 90's. It works under t
 he assumption that d is at least 7 and d does not divide n+1\, which in pa
 rticular excludes the Calabi-Yau case in all dimensions. We prove that the
  generic Torelli theorem for hypersurfaces holds with finitely many except
 ions. A key tool is the notion of Schiffer variation of a hypersurface and
  how to characterize them by looking at the variation of Hodge structure a
 long them.\n
