Abstract
Let R be a normal, equi-codimensional Cohen–Macaulay ring of dimension with a canonical module . We give a sufficient criterion that establishes a derived equivalence between the noncommutative crepant resolutions of R . When , this criterion is always satisfied and so all noncommutative crepant resolutions of R are derived equivalent. Our method is based on cluster tilting theory for commutative algebras, developed by Iyama and Wemyss (2010).
