Title: Mirror symmetry and crepant resolution conjecture for disks
Abstract: We will continue the localization computation of open Gromov-Witten invariants for toric Calabi-Yau 3-orbifolds from last time, and discuss an explicit formula for the disk potential obtained via mirror symmetry. Using this formula, we will see an instance of Ruan's crepant resolution conjecture for disk invariants following Ke-Zhou. The discussion will be accompanied by the explicit example of [C^2/Z_3] \times C and its (partial) resolutions.
