| Let R and T be Noetherian complete semilocal rings, R T a ring homomorphism. In this paper, we show that if T is a finitely generated or Artinian R-module, M is a G-Matlis reflexive R-module, then for all n>0, ExtＲｎ(T,M), ExtＲｎ(M,T), TorＲｎ(T,M) and TorＲｎ(M,T) are G-Matlis reflexive T-modules. These results generalize the results of R.Belshoff. |
