Let I be an ideal of a commutative Noetherian ring R such that the R-modules HIi(M) are I-cofinite, for all finitely generated R-modules M and all i∈ℕ0. Let M and N be two I-cofinite R-modules and ...

Let (R,m) be a complete Noetherian local ring and let M be a generalized Cohen–Macaulay R-module of dimension d ≥ 2. We show that $$ D\left({H}_m^d\left(D\left({H}_m^d\left({D}_m(M)\right)\right)\right)\right)\approx {D}_m(M), $$ where D = Hom(

Let n and t be non-negative integers, R a commutative Noetherian ring with dim(R)≤n+2,a an ideal of R, M and N finite R-modules, and X an arbitrary R-module. We prove that if ExtRi(M/aM,X) is an FD...

Let R be a commutative Noetherian ring with nonzero identity, 𝔞 an ideal of R, and n a nonnegative integer. For an arbitrary R-module X which is not necessarily finite, we prove the following results: (i) f𝔞n(X)= inf{i∈ℕ0: H𝔞i(X) is not
