摘要
设R是一个noether环,I是R的一个理想,设M是一个有限生成的R模,cd(I,M) = t≥0,并设L是M的最大子模,使得cd(I,L) < cd(I,M)。可以看出,在以下情况下,AnnR Ht I (M) = AnnRM/L:(I) dimM/IM≤1。(ii) dimR/I≤1。(iii)当I≥2时,r模Hi I (M)为Artinian。(iv)当I≥2时,R模Hi I (R)为Artinian。(v) cd(I,M)≤1。(vi) cd(I,R)≤1。(vii) r模hti (M)是Artinian和I- finite。这些断言肯定地回答了Atazadeh等人在[2]中在某些特殊情况下提出的问题。”
"COFINITENESS AND ANNIHILATORS OF TOP LOCAL COHOMOLOGY MODULES"
"Let R be a Noetherian ring and I be an ideal of R. Let M be a finitely generated R-module with cd(I,M) = t ≥ 0 and assume that L is the largest submodule of M such that cd(I,L) < cd(I,M). It is shown that AnnR Ht I (M) = AnnRM/L in each of the following cases: (i) dimM/IM ≤ 1. (ii) dimR/I ≤ 1. (iii) The R-module Hi I (M) is Artinian for each i ≥ 2. (iv) The R-module Hi I (R) is Artinian for each i ≥ 2. (v) cd(I,M) ≤ 1. (vi) cd(I,R) ≤ 1. (vii) The Rmodule Ht I (M) is Artinian and I-cofinite. These assertions answer affirmatively a question raised by Atazadeh et al. in [2], in some special cases."
期刊介绍:
The journal MATHEMATICAL REPORTS (formerly STUDII SI CERCETARI MATEMATICE) was founded in 1948 by the Mathematics Section of the Romanian Academy. It appeared under its first name until 1998 and received the name of Mathematical Reports in 1999. It is now published in one volume a year, consisting in 4 issues. The current average total number of pages is 500.
Our journal MATHEMATICAL REPORTS publishes original mathematical papers, written in English. Excellent survey articles may be also accepted. The editors will put strong emphasis on originality, quality and applicability.
