摘要
Let A be a Noetherian ring. It is shown that any finite A-module M of finite Krull dimension with finite Cousin complex cohomologies has a uniform local cohomological annihilator. The converse is also true for a finite module M satisfying (S-2) which is over a local ring with Cohen-Macaulay formal fibers. (C) 2007 Elsevier Inc. All rights reserved.
