摘要：

In this article, Gorenstein FP-injective modules are introduced and investigated. A left R-module M is called Gorenstein FP-injective if there is an exact sequence ... -> E-1 -> E-0 -> E-0 -> E-1 -> ... of FP-injective left R-modules with M = ker (E-0 -> E-1) such that Hom(R)(P, -) leaves the sequence exact whenever P is a finitely presented left R-module with pd(R)(P) < infinity. Some properties of Gorenstein FP-injective modules are obtained. Several well-known classes of rings are characterized in terms of Gorenstein FP-injective modules.
