Members’ Seminar

There is a remarkable parallel between the theory of Coxeter groups (think of the symmetric group Sn or the dihedral group Dn) and matroids (think of your favorite graph or vector configuration). After giving an overview of the similarity, I will report on recent progress on the nonnegativity conjecture and the top-heavy conjecture for arbitrary matroids. Joint work with Tom Braden, Jacob Matherne, Nick Proudfoot, and Botong Wang.
