Mathematik und Informatik

Take G an abelian subgroup of SL(n,C) (n<=3). Craw and Ishii show varying the stability condition on a moduli space of McKay quiver representations recovers all projective crepant resolutions of the singularity A^n/G. In this talk we will recover the stack [A^n/G] (a noncommutative crepant resolution) from the McKay quiver. We will then relate it to a commutative resolution via a change of stability conditions on a moduli space of refined representations of the McKay quiver.
