Participating: Thomas Lam
Abstract: Polypositroids are polytopes that are simultaneously alcoved
polytopes and generalized permutahedra. Whereas positroids are
"positive" matroids, polypositroids are "positive" polymatroids. I
will discuss the parametrization and classification of polypositroids,
and the relation to certain discrete surfaces we call membranes. This
is joint work with Alex Postnikov.
