We introduce the class of dominant Auslander–Gorenstein algebras as a generalisation of higher Auslander algebras and minimal Auslander–Gorenstein algebras, and give their basic properties. We also introduce mixed (pre)cluster tilting modules as a generalisation of (pre)cluster tilting modules, and establish an Auslander type correspondence by showing that dominant Auslander–Gorenstein (respectively, Auslander-regular) algebras correspond bijectively with mixed precluster (respectively, cluster) tilting modules. We show that every trivial extension algebra T (A) of a d-representation-finite algebra A admits a mixed cluster tilting module and show that this can be seen as a generalisation of the well-known result that d-representationfinite algebras are fractionally Calabi–Yau. We show that iterated SGC-extensions of a gendo-symmetric dominant Auslander–Gorenstein algebra admit mixed precluster tilting modules.
