TitleDeterminantal schemes and pure O-sequences
Author(s) Alexandru Constantinescu, Matey Mateev
TypeArticle in Journal
AbstractAbstract We prove that if a standard determinantal scheme is level, then its h-vector is a log-concave pure O-sequence, and conjecture that the converse also holds. Among other cases, we prove the conjecture in codimension two, or when the entries of the corresponding degree matrix are positive. We also find formulae for the h-vector in terms of the degree matrix.
