拉伸理想的约化数

The reduction number of stretched ideals

Kazuho Ozeki

摘要:

理想的伴随分次环的同调性质是交换代数和代数几何中的一个重要问题。在Cohen-Macaulay局部环$(A,\mathfrak{m})$中,当约化数达到几乎极小值时,本文研究了拉伸$\mathfrak{m}$ -准素理想的伴随分次环的几乎Cohen-Macaulay性.作为应用,我们给出了小约化数的拉伸$\mathfrak{m}$ -准素理想的相关分次环的完整刻划。

英文摘要:

The homological property of the associated graded ring of an ideal is an important problem in commutative algebra and algebraic geometry. In this paper we explore the almost Cohen-Macaulayness of the associated graded ring of stretched $\mathfrak{m}$-primary ideals in the case where the reduction number attains almost minimal value in a Cohen-Macaulay local ring $(A,\mathfrak{m})$. As an application, we present complete descriptions of the associated graded ring of stretched $\mathfrak{m}$-primary ideals with small reduction number.
