Kuznetsov's categorical McKay conjecture for quotient singularities
Kuznetsov's categorical McKay conjecture for quotient singularities
Let be a smooth quasi-projective variety, and let be a finite subgroup of such that is -equivariantly locally trivial. Let be any resolution of singularities. Kuznetsov's conjecture. There exists an admissible fully faithful embedding
In particular, if is a crepant resolution of , there is an equivalence
This is the stated categorical form of the McKay correspondence for quotient singularities. The last equivalence is known when , or when is symplectic and acts by symplectic automorphisms; the general assertion remains open.
