On some properties of pure morphisms of commutative rings

Abstract

We prove that pure morphisms of commutative rings are effective double-struck a-descent morphisms where a is a (commutative rings) op-indexed category given by (i) finitely generated modules, or (ii) flat modules, or (iii) finitely generated flat modules, or (iv) finitely generated projective modules. © Bachuki Mesablishvili, 2002.
