Generalized permutohedra, h-vectors of cotransversal matroids and pure O-sequences (extended abstract)
Abstract : Stanley has conjectured that the h-vector of a matroid complex is a pure O-sequence. We will prove this for cotransversal matroids by using generalized permutohedra. We construct a bijection between lattice points inside a $r$-dimensional convex polytope and bases of a rank $r$ transversal matroid.
