Talking About Combinatorial Objects Student Seminar: Grassmannians, Matroids, and Flags

Seminar | December 1 | 1-2 p.m. | 748 Evans Hall

 Charles Wang, UC Berkeley

 Department of Mathematics

We will study the relationship between matroids and the geometric structure of the Grassmannian in terms of Schubert cells and other related objects. We will briefly extend these geometric ideas to the more general setting of flag varieties and flag matroids. Time permitting, we will discuss various ways to realize matroid polytopes for matroids associated to the Grassmannian.
