Türk Matematik Derneği Seçkin Seminerler SerisiRationality Criteria for Hypersurfaces Brendan Hassett An algebraic variety is rational if it admits a birational parametrization by affine space. Stereographic projections of spheres are examples. We still do not know which cubic hypersurfaces are rational! We survey recent results – using classical geometry, Hodge theory, and newer techniques like derived categories – as well as natural open questions. Zoom admin 16.10.2023 |
