Abstract
Let and be commutative Noetherian algebras over an arbitrary field such that is Noetherian. We consider ideals and of and , respectively, as well as nonzero finitely generated modules and over and , respectively. In this paper, we investigate certain algebraic properties of the -module , which are often inherited from the properties of the -module and the -module . Specifically, we provide characterizations for the Cohen-Macaulayness, generalized Cohen-Macaulayness, and sequentially Cohen-Macaulayness of with respect to the ideal , in terms of the corresponding properties for and with respect to and , respectively.
