Cohen-Macaulayness of formal fibers and dimension of local cohomology modules

Tran Do Minh Chau

Let $(R, m)$ be a Noetherian local ring, $M$ a finitely generated $R$ -module of dimension $d$ . Set $a (M) := a_{0} (M) \dots a_{d - 1} (M)$ , whe…

Ascent and descent of Artinian module structures under flat base changes

Tran Do Minh Chau, Le Thanh Nhan

Let $I ¨ : R \to S$ be a flat local homomorphism between commutative Noetherian local rings. In this paper, the ascent and descent of Artinian module structures between $R$ an…
