Abstract

We prove that if II is a monomial ideal with linear quotients in a ring of polynomials SS in nn indeterminates and depth(S/I)=n2\operatorname{depth}(S/I)=n-2, then sdepth(S/I)=n2\operatorname{sdepth}(S/I)=n-2 and, if II is squarefree, hdepth(S/I)=n2\operatorname{hdepth}(S/I)=n-2. Also, we prove that sdepth(S/I)depth(S/I)\operatorname{sdepth}(S/I)\geq \operatorname{depth}(S/I) for a monomial ideal II with linear quotients which satisfies certain technical conditions.
