| 15:30 - 17:00 Geometry and Topology Weekly Seminar On the Postulation of Scheme Theoretic Unions of Linear Subspaces of Projective Space School MATHEMATICS A fundamental problem in Algebraic Geometry for projective schemes X is postulation problem. In fact to understand the geometry of X as an embedded scheme, one of the first points of interest is considering the postulation problem, i.e. determining the number of conditions imposed by asking hypersurfaces of any degree to contain X. There is an expected number of conditions- in this situation the scheme X is said to have good postulation. So a natural question to ask is: when does X have good postulation, and if it is not, why not? In the case when X is a scheme supported on unions of generic linear subspaces of a projective space there is ... |
