SUMMARY |
|
|
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.
