TitleGröbner bases of ideals cogenerated by Pfaffians
Author(s) Emanuela De Negri, Enrico Sbarra
TypeArticle in Journal
AbstractWe characterise the class of one-cogenerated Pfaffian ideals whose natural generators form a Gröbner basis with respect to any anti-diagonal term order. We describe their initial ideals as well as the associated simplicial complexes, which turn out to be shellable and thus Cohen–Macaulay. We also provide a formula for computing their multiplicity.
