| Oct 21, 2018 at 15:14 | comment | added | Aaron Dall | Note that the generators of Alexander dual $I^{[4,3,3]}$ are precisely the monomials $\mathbf{x}^{\mathbf{K} + \mathbf{1}}/\mathbf{x}^{\mathbf{b}}$ for $\mathbf{x}^{\mathbf{b}} \in \mathrm{MonSoc}(I)$. This is similar to Proposition 1 on page 5 of this paper where the facet ideal of a matroid is expressed as the Stanley-Reisner ideal of the Alexander dual of the (independence complex) of the dual matroid. | |
