Generalized permutohedra, \(h\)-vectors of cotransversal matroids and pure \(O\)-sequences
The electronic journal of combinatorics, Tome 20 (2013) no. 3
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 an r-dimensional convex polytope and bases of a rank r transversal matroid.
