Abstract :Let X be a class of right R-modules that contains all projective right R-modules. The notion of X-Gorenstein projective modules was introduced by D. Bennis and K. Ouarghi (X-Gorenstein projective modules, International Mathematical Forum 5 (10), 487–491, 2010). In this paper, we introduce Y-Gorenstein injective right R-modules and Y-Gorenstein flat left R-modules, where Y is a class of right R-modules that contains all injective right R-modules. We show that the principal results on Gorenstein modules remain true for X-Gorenstein projective right R-modules, Y-Gorenstein injective right R-modules and Y-Gorenstein flat left R-modules.Keywords : X-Gorenstein projective modules, Y-Gorenstein injective modules, Y-Gorenstein flat modules, 2000 AMS Classification: 16 E 10
