交换代数 2024-05-15 v5

摘要

我们证明:若 II 是含 nn 个未定元的多项式环 SS 中具有线性商的单项式理想,且 depth(S/I)=n2\operatorname{depth}(S/I)=n-2,则 sdepth(S/I)=n2\operatorname{sdepth}(S/I)=n-2,并且若 II 为平方自由理想,则 hdepth(S/I)=n2\operatorname{hdepth}(S/I)=n-2。此外,我们证明:对于满足某些技术条件的具有线性商的单项式理想 II,有 sdepth(S/I)depth(S/I)\operatorname{sdepth}(S/I)\geq \operatorname{depth}(S/I)
