A topological gauged sigma-model
arXiv:hep-th/0502152
Abstract
We describe a topological field theory that studies the moduli space of solutions of the symplectic vortex equations. It contains as special cases the topological sigma-model and topological Yang-Mills over Kahler surfaces. The correlation functions of the theory are closely related to the recently introduced Hamiltonian Gromov-Witten invariants.
