In this talk, I will discuss about new algebraic invariants for algebraic orbifolds: orbifold motivic cohomology and orbifold higher K-theory. These invariants come out as a consequence of the obstruction bundles and the virtual fundamental classes in Gromov-Witten theory. I will also explain how these invariants relate to motivic cohomology and K-theory of (crepant) resolutions of singularities of the coarse moduli spaces of orbifolds.

This is a joint work with Fu Lei.
