Given a vector bundle on a Kahler manifold and a characteristic class, T. Coates and A. Givental studied Gromov-Witten invariants twisted by these data. They proved a quantum Riemann-Roch theorem which relates the twisted invariants with the untwisted ones. In this talk we will discuss a generalization of their results to orbifold target spaces.Date: Thursday, January 26, 2006
