The quantum equivariant cohomology of toric manifolds through mirror symmetry
J. M. Baptista
Using mirror symmetry as described by Hori and Vafa, we compute the quantum equivariant cohomology ring of toric manifolds. This ring arises naturally in topological gauged sigma-m…

Twisting gauged non-linear sigma-models
J. M. Baptista
We consider gauged sigma-models from a Riemann surface into a Kaehler and hamiltonian G-manifold X. The supersymmetric N=2 theory can always be twisted to produce a gauged A-model.…

A topological gauged sigma-model
J. M. Baptista
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 t…
