Keywords: | Finite fields (Algebra);Rings (Algebra);Homology theory | Issue Date: | 2000 | Publisher: | world scientific | Abstract: | Throughout this paper all rings are associative with identity and all modules are unitary. We denote the category of all right R-modules by Mod-R and for any M ∈ Mod-R, σ[M] stands for the full subcategory of Mod-R whose objects are submodules of M-generated modules (see [12]). Given a module XR the injective hull of X in Mod-R (resp., in σ[M]) is denoted by ... ∗The author was partially supported by Birzeit University under grant # 235-17-98-9.
