[Günter Rote <rote@inf.fu-berlin.de>]

Our next Monday Lecture takes place on July 3 at 16:00 sharp at FU Berlin.

*_Location_*

*Great Lecture Hall - Ground Floor*
Freie Universität Berlin
Takustr. 9
14195 Berlin

*_Time_: *Monday, July 3, 2023, 16:00*

*_Lecture_: Dante Luber (TU Berlin)

*_Title_: Initial degenerations of the Grassmannian
          via matroid subdivisions of hypersimplices

*_Abstract_:*

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.

*_Tea break_:*

Before the talk, at 15:30, there will be a coffee and tea "break" at the usual
place, Room 134 (glass door, straight from the stairs) in the first floor.
