Let be a commutative Noetherian ring, an ideal of . Let be an integer and an -module such that is minimax for all . We prove that if is (or weakly Laskerian) for all , then the -modules are -cominimax for all and is minimax for . Let be a finitely generated -module. We prove that and are -cominimax for all and whenever is minimax and is (or weakly Laskerian) for all .
