摘要：
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-? has linear quotients. As a consequence, I is sequentially Cohen-Macaulay if and only if I is shellable.
