On the shape of a pure O-sequence

Memoirs AMS 218 (2012), no. 2024, vii + 78 pp An order ideal is a finite poset X of (monic) monomials such that, whenever M is in X and N divides M, then N is in X. If all, say t, maximal monomials of X have the same degree, then X is pure (of type t). A pure O-sequence is the vector, h=(1,h_1,...,h...
