Abstract
Let R be a commutative Noetherian complete local ring, I an ideal of R, and M, N Matlis reflexive R-modules such that Supp(N) ⊆ V(I). In this note, among other things, we show that is Matlis reflexive for all i and j when one of the following conditions holds:
-
dim(R/I) = 1;
-
I is a principal ideal;
-
dim(R) ≤ 2.
