摘    要:设R是含幺Noether交换环,I是R的理想,R-模M是弱拉斯克的.本文给出了I相对于M的次的刻画:gradeM(I)=inf{r∈N0|HI^T(M)≠0}.本文的另一主要结论是:设i是非负整数,若i是第一个使得局部上同调模HiI(M)不是有限生成的整数,那么我们证明AssR(H^iI(M))是有限集.

关 键 词:局部上同调  弱拉斯克模  相伴素理想

Abstract:Let R be a commutative Noetherian ring with identity. Let I be an ideal of R, and M a weakly Laskerian R-module. In this article we give an expression of the grade of I respect to M: gradeM (I) = inf{ r ∈ N0 |HI^T(M) ≠0}. Another result of this article is that:Let i he a non-negative integer, if i is the first intenger such that the local eohomology module H^iI (M) is not finitely generated, then we show that Assg(H^iI(M) ) is a finite set.
Keywords:local cohomology  weakly Laskerian modules  associated prime ideals  grade
