摘      要: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 relationship between the Artinianness of HI^i(M, N) and the Artinianness of HI^i(N). Then, we get that HI^d(M, N) is I-cofinite, if (R, m) is a d-dimensional Gorenstein local ring.
