单项理想的素滤子与极化

Prime filtrations of monomial ideals and polarizations

Ali Soleyman Jahan

摘要:

证明了至多3个变量的多项式环中的所有单项理想都是相当干净的,并且任意单项理想$I$是相当干净的当且仅当它的极化$I^p$是干净的。这就给出了一个关于相当干净的单项式理想的算术次数的新刻画,并且它也意味着一个多重复形是可壳的,当且仅当对应于它的极化的单纯复形是(非纯)可壳的。我们还讨论了与素过滤有关的斯坦利分解。

英文摘要:

We show that all monomial ideals in the polynomial ring in at most 3 variables are pretty clean and that an arbitrary monomial ideal $I$ is pretty clean if and only if its polarization $I^p$ is clean. This yields a new characterization of pretty clean monomial ideals in terms of the arithmetic degree, and it also implies that a multicomplex is shellable if and only the simplicial complex corresponding to its polarization is (non-pure) shellable. We also discuss Stanley decompositions in relation to prime filtrations.
