Abstract

Throughout R is a Noetherian local ring. In this paper we study cohomological dimension of an R-module M with respect to a pair of ideals and some of its relations with the attached prime ideals of M and the cohomological dimension of M with respect to an ideal. Furthermore, we generalize some results of [5] in particular, Theorem 2.8.
