   Abstract:
   Let $G$ be a finite subgroup of $SL(3, \IC)$ acting with an isolated singularity on $\IC^3$. A crepant resolution of $\IC^3/G$ comes together with a set of tautological line bundles associated to each irreducible representation of $G$. In this note we give a formula for the triple product of the first Chern class of the tautological bundles in terms of both the geometry of the crepant resolution and the representation theory of $G$. From here we derive the way these triple products change when we perform a flop.
