Dorin Popescu and Andrei Zarojanu: Three generated, squarefree, monomial ideals, p.359-368

Abstract:

Let I⊋J be two squarefree monomial ideals of a polynomial algebra over a field generated in degree $\geq d$, resp. $\geq d+1$ . Suppose that $I$ is generated by three monomials of degrees $d$. If the Stanley depth of $I/J$ is $\leq d+1$ then the usual depth of $I/J$ is $\leq d+1$ too.

Key Words: Monomial Ideals, Depth, Stanley depth.
