Noncommutative resolutions of discriminants
arXiv:1702.00791 · doi:10.1090/conm/705/14199
Abstract
We give an introduction to the McKay correspondence and its connection to quotients of 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.
