Abstract

In this paper we characterize the relative Gorenstein weak global dimension of the generalized Gorenstein FPn\mathrm{FP}_n-flat RR-modules and Projective Coresolved FPn\mathrm{FP}_n-flat RR-modules recently studied by S. Estrada, A. Iacob, and M. A. P\'erez. As application we prove that the weak global dimension that comes from the Gorenstein FPn\mathrm{FP}_n-flat modules is finite over a Gorenstein nn-coherent ring and coincide with the flat dimension of the right FPn\mathrm{FP}_n-injective RR-modules. This result extends the known for Gorenstein flat modules over Iwanaga-Gorenstein and Ding-Chen rings. We also show that there is a close relationship between the global dimensions of the generalized Gorenstein FPn\mathrm{FP}_n-projectives and FPn\mathrm{FP}_n-injectives and the relative Gorenstein weak global dimension presented here, obtaining in the process a balanced pair.
