TITLE	Derived McKay Correspondence and Non-Commutative Deformations
ABSTRACT	The derived MacKay correspondence conjecture states that there is an equivalence of triangulated categories between commutative and non-commutative crepant resolutions of singularities. It is proved in dimensions at most 3 or for toric singularities. We investigate how the derived McKay correspondence extends under non-commutative deformationso f commutative and non-commutative crepant resolutions in the example of toric surface singularities.
