SUMMARY:Workshop / Seminar:Learning Seminar in Algebraic Combinatorics: Bergman fans and their subdivisions
DESCRIPTION:In this talk we first introduce another way of constructing new matroids from a given one M\, by minimizing the linear functional w \cdot x over x in the matroid polytope of M\, for a fixed w in R^n. We then use this to define the Bergman fan of a given matroid\, which are spaces of weights w whose corresponding matroids do not contain loops. To understand the topology of the Bergman fan\, we introduce a combinatorial gadget called phylogenetic trees which can be used to parametrize the Bergman fan\, and give a nice subdivision of it.

SUMMARY:Workshop / Seminar:Work for Housing Equity with Justice InDeed!
DESCRIPTION:Looking for a tangible way to improve equity in Washtenaw County? \n\nCome join Justice InDeed for a collaborative session to identify & transcribe racially restrictive covenants on home deeds in Washtenaw County. During the session\, we will be working together to build a database and map for affected properties all over the County\, helping us better reckon with our complete history. No experience is necessary\, just bring your enthusiasm and willingness to help make a difference in our community! This event is a partnership between Ann Arbor Housing For All and FutureRoot. \n\nDon't miss out on this opportunity to contribute to a great cause and connect with like-minded individuals. See you there!
