An example of crepant resolution conjecture in two steps
arXiv:0905.1725
Abstract
We study the relation among the genus 0 Gromov-Witten theories of the three spaces , where $\mathcal{X}=[\c^2/\z_3]$, is obtained by a weighted blowup at the stacky point of , and is the crepant resolution of the singularity. We formulate and verify a statement similar to the Crepant Resolution Conjecture of Bryan and Graber.b
