摘要：
We give an introduction to the McKay correspondence and its connection to quotients of C-n by finite reflection groups. This yields a natural construction of noncommutative resolutions of the discriminants of these reflection groups. This paper is an extended version of E. F.'s talk with the same title delivered at the ICRA.
