Northeastern Mathematical Journal 2007年 第1期23卷 87-94页
作者: 褚利忠 Department of Mathematics Suzhou University Suzhou 215006
In this paper, let (R, m) be a Noetherian local ring, I lohtain in R an ideal, M and N be two finitely generated modules. Firstly, we study the properties of HI^t(M), t = f-depth(I, M) and discuss the relationsh... 详细信息
