模的上有限性与局部上同调

Cofiniteness of modules and local cohomology

Hajar Sabzeh, Reza Sazeedeh

摘要:

设$A$是交换诺特环,$\mathfrak a$是$A$的理想,$n$是非负整数.本文研究了一类$A$ -模$\mathcal{S}_{n}(\mathfrak{a})$,得到了一个模属于$\mathcal{S}_{n}(\mathfrak{a})$的充分条件.此外,我们还研究了当$\dim A/\frak a\geq 3$时局部上同调模的上有限性.

英文摘要:

Let $A$ be a commutative noetherian ring, let $\mathfrak a$ be an ideal of $A$ and let $n$ be a non-negative integer. In this paper, we study $\mathcal{S}_{n}(\mathfrak{a})$, a certain class of $A$-modules and we find some sufficient conditions so that a module belongs to $\mathcal{S}_{n}(\mathfrak{a})$. Moreover, we study the cofiniteness of local cohomology modules when $\dim A/\frak a\geq 3$.
