Algebraic Geometry Research Seminar

Organiser: Balázs Szendrői

  • June 20 – June 21: Algebraic Geometry workshop
  • Monday June 23, 15:00 – 16:30 in SR12. Aline Zanardini (EPFL), GIT for linear systems of hypersurfaces
    •  In this talk, we will consider the problem of classifying linear systems of hypersurfaces inside projective space and up to projective equivalence. I will report on a possible approach to solving this problem via geometric invariant theory. I will further illustrate how such an approach can be applied to some relevant geometric examples. This is based on joint work with Masafumi Hattori.
