Ee. Enochs et Omg. Jenda, MOCK FINITELY GENERATED GORENSTEIN INJECTIVE-MODULES AND ISOLATED SINGULARITIES, Journal of pure and applied algebra, 96(3), 1994, pp. 259-269
In this paper, we study mock finitely generated modules and Gorenstein
injective modules which are a generalization of finitely generated mo
dules and injective modules respectively. We also discuss invariants f
or minimal injective resolvents which are analogous to Bass' invariant
s for minimal injective resolutions. We use these invariants to charac
terize Gorenstein isolated singularities in terms of mock finitely gen
erated Gorenstein injective modules.
