Bernd Sturmfels (MPI-MiS): The Two Lives of the Grassmannian

Frankfurt, Robert-Mayer-Str. 10, Raum 711 groß

Oberseminar Algebra und Geometrie Abstract: The Grassmannian parametrizes linear subspaces of a real vector space. It is both a projective variety (via Plücker coordinates) and an affine variety (via orthogonal projections). We examine these two representations, through the lenses of linear algebra, commutative algebra, and statistics.
