有限生成模的极大深度性质

Maximal depth property of finitely generated modules

Ahad Rahimi

摘要:

设$(R,\mathfrak{m})$是一个Noether局部环,$M$是一个Noether生成的$R$ -模.我们说$M$具有最大深度,如果存在$M$的关联素数$\mathfrak{p}$,使得深度为$M=\dim R/\mathfrak{p}$。本文研究了具有极大深度的有限生成模。结果表明,在一些重要的模运算下,最大深度性质保持不变。对具有极大深度的广义Cohen-Macaulay模进行了分类.最后,对$i<\mathrm{dim} M$考虑了$H^i_{\mathfrak{m}}(M)$的附加素数.

英文摘要:

Let $(R,\mathfrak{m})$ be a Noetherian local ring and $M$ a finitely generated $R$-module. We say $M$ has maximal depth if there is an associated prime $\mathfrak{p}$ of $M$ such that depth $M=\dim R/\mathfrak{p}$. In this paper, we study finitely generated modules with maximal depth. It is shown that the maximal depth property is preserved under some important module operations. Generalized Cohen--Macaulay modules with maximal depth are classified. Finally, the attached primes of $H^i_{\mathfrak{m}}(M)$ are considered for $i<\mathrm{dim} M$.
