Title: Twisted Gromov-Witten invariants
Date (JST): Thu, Oct 11, 2012, 15:30 - 17:00
Place: Seminar Room A
Abstract: I will introduce twisted Gromov-Witten invariants of a compact, complex orbifold X: they are defined by capping the virtual fundamental class(es) of the moduli spaces of stable maps X_{g,n,d} with multiplicative characteristic classes of push-forwards of certain "tautological" bundles along the universal curve. I will express twisted GW invariants of X in terms of untwisted (i.e. usual GW invariants) ones using Givental's Lagrangian cone formalism. This generalizes previous work of Coates-Givental and Tseng.
