Let (R,𝔪) be a commutative Noetherian complete local ring and I be a proper ideal of R. Suppose that M is a nonzero I-cofinite R-module of Krull dimension n. In this paper, it shown that dim R/(I +AnnRH𝔪n(M)) = n. As an application of this result, it is shown that dim R/(I +𝔭) = n, for each 𝔭 AttRH𝔪n(M). Also it shown that for each j 0 the submodule Σj(M) := {K : K M and dim K j} of M is I-cofinite, dim R/(I +AnnRH𝔪j(M/Σ j(M))) < j and dim R/(I +AnnRH𝔪j(M)) j, whenever the category of all I-cofinite R-modules is an Abelian subcategory of the category of all R-modules. Also some applications of these results will be included.

cofinie 模的 Artinian 局部上同调模

(R,𝔪)是一个可交换的 Noetherian 完全局部环,并且一世成为正确的理想R. 假设是一个非零一世-有限的R-克鲁尔维度的模块n. 在这篇论文中,它表明暗淡 R/(一世 +RH𝔪n()) = n.作为该结果的应用,表明暗淡 R/(一世 +𝔭) = n, 对于每个𝔭 攻击者RH𝔪n().它还表明,对于每个j 0子模块Σj() = {ķ ķ 暗淡 ķ j}一世-有限,暗淡 R/(一世 +RH𝔪j(/Σ j())) < j暗淡 R/(一世 +RH𝔪j()) j,当所有的类别一世-有限的R-modules 是所有类别的阿贝尔子类别R-模块。还将包括这些结果的一些应用。
