SUMMARY:Recreational / Games:Kreativwerkstatt
DESCRIPTION:Chat in German and express yourself creatively. Crafting\, coloring\, painting\, drawing\, knitting\, sewing\, crochet\, embroidery\, origami? You will combine speaking German\, any level welcome\, beginners included\, and creatively expressing yourself. You are encouraged to bring your own materials or (ongoing) projects\, but we will also provide some materials and prompts each week. Contact Laura Okkema (lokkema@umich.edu) or Iris Zapf-Garcia (iriszaga@umich.edu.) with questions.

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.
