Abstract
Let be an ideal of a commutative noetherian ring , a Serre subcategory of -modules satisfying the condition and the subcategory of finitely generated -modules. In this paper, we continue the study of --cofinite modules with respect to the extension subcategory , show that some classical results of -cofiniteness hold for --cofiniteness in the cases or , where is a positive integer. We also study --cofiniteness of local cohomology modules and the modules and .
