Abstract

This paper is concerned with the relation between local
cohomology modules defined by a pair of ideals and Serre classes of
R-modules. Let R be a commutative Noetherian ring, I , J be two
ideals of R and M be an R-module. Let a 2 ˜W (I, J) and t 2 N0
be such that Extt
R(R/a,M) 2 S and Extj
R(R/a,Hi
I,J (M)) 2 S for all
i < t and all j > 0. Then for any submodule N of Ht
I,J (M) such that
Ext1
R(R/a,N) 2 S, we obtain HomR(R/a,Ht
I,J (M)/N) 2 S.
