The (generalized) McKay correspondence relates the representation theory of a finite subgroup G<SL(n,C) with the geometry of a crepant resolution of C^n/G. Lately, this correspondence has been studied at the level of derived categories and in the enumerative geometry of Calabi-Yau three-folds (Gromov-Witten/Donaldson-Thomas theories). More recently, Oh-Thomas developed an algebraic machinery to count sheaves on Calabi-Yau 4-folds. We show how theMcKay correspondence naturally (and conjecturally) extends to this new setting, and how it specializes to many enumerative results already known in the literature. This is joint work (in progress!) with Y. Cao and M. Kool.
