I'll then explain how, when we study tropicalizations of linear spaces, we get the Bergmann complex of a matroid, which Yucong spoke about last week. Finally, I'll try to motivate the wonderful compactification of a hyperplane arrangement complement. Expect a fairly informal, loosely prepared, talk.",https://events.umich.edu/event/127661,"East Hall",4088,"East Hall",,,"Learning Seminar in Algebraic Combinatorics - Department of Mathematics"
