Let be a Cohen-Macaulay normal domain. A non commutative crepant resolution (NCCR) of is an -algebra of the form $\Gamma = End_A(M)MA\Gamma$ is maximal Cohen-Macaulay as an -module and for all primes of . We give bountiful examples of equi-characteristic Cohen-Macaulay normal local domains and mixed characteristic Cohen-Macaulay normal local domains having NCCR. We also give plentiful examples of affine Cohen-Macaulay normal domains having NCCR.
