Abstract

Let RR be a commutative noetherian ring with a semi-dualizing module CC. The Auslander categories with respect to CC are related through Foxby equivalence: \xymatrix@C=50pt{\mathcal {A}_C(R) \ar@<0.4ex>[r]^{C\otimes^{\mathbf{L}}_{R} -} & \mathcal {B}_C(R) \ar@<0.4ex>[l]^{\mathbf{R}\mathrm{Hom}_{R}(C, -)}}. We firstly intend to extend the Foxby equivalence to Cartan-Eilenberg complexes. To this end, C-E Auslander categories, C-E W\mathcal{W} complexes and C-E W\mathcal{W}-Gorenstein complexes are introduced, where W\mathcal{W} denotes a self-orthogonal class of RR-modules. Moreover, criteria for finiteness of C-E Gorenstein dimensions of complexes in terms of resolution-free characterizations are considered.
