Abstract
Let be a commutative noetherian ring, let and be two ideals of ; and let be a Serre subcategory of -modules. We give a necessary and sufficient condition by which satisfies and conditions. As an conclusion we show that over a artinian local ring, every Serre subcategory satisfies condition. We also show that is closed under extension of modules. If is a torsion subcategory, we prove that satisfies condition. We prove that condition can be transferred via rings homomorphism. As some applications, we give several results concerning with Serre subcategories in local cohomology theory.
