Topic:

Let G be a finite subgroup of SU(2). The classical McKay correspondence
describes the cohomology ring of Y the minimal resolution of C2/G in
terms of the representation theory of G. We give a description of the
quantum cohomology of Y in terms of a root system canonically
associated to G. Implications for the Crepant Resolution Conjecture may
be discussed.
