Lecture by Dante Luber (Technische Universität Berlin): Initial degenerations of Grassmannian via matroid subdivisions of hypersimplices
Nonempty initial degenerations of the Grassmannian are induced by weight functions in its tropicalization. On the other hand, the same weight function induces a regular matroidal subdivision of the hypersimplex. Hence, we study initial degenerations of the (3,8) Grassmannian via matroidal subdivisions of the (3,8) hypersimplex. Our techniques employ tropical, algebraic, and polyhedral geometry, as well as matroid theory, commutative algebra, and computation.
Before the talk, at 15:30, there will be a tea "break" at the usual place, Room 134 in the first floor (glass door, facing the exit from the stairway).
