11:00 - 13:00 Commutative Algebra WebinarA Characterization of Sequentially Cohen-Macaulay Matroidal Ideals School MATHEMATICS Let $R=K[x_1,...,x_n]$ be the polynomial ring in $n$ variables over a field $K$ and $I$ be a matroidal ideal of $R$. We show that $I$ is sequentially Cohen-Macaulay if and only if the Alexander dual $I^{vee}$ has linear quotients. As consequence, $I$ is sequentially Cohen-Macaulay if and only if $I$ is shellable. https://zoom.us/join Meeting ID: 908 611 6889 Passcode: 362880 ... |
