The associativity of the Chen-Ruan product follows from a property of the obstruction bundles discovered by Chen-Ruan in using the gluing construction in Gromov-Witten theory. Thanks for voting!

Recall that an orbifold is a paracompact Hausdorff space equipped with a compatible system of orbifold atlases locally modeled on quotient spaces of Euclidean spaces by finite group actions.Video: Stringy k theory and the chern character definition Weakness: Character Development WorkshopAlmost complex orbifolds are those orbifolds with local models given by a finite group acting unitarily on complex spaces. The full orbifold K-theory was further studied by Goldin, Harada, Holm and Kimura for abelian symplectic quotients in. The notion of orbifold was first introduced by Satake under the name V-manifold.
