Testing S-duality with non-orientable surfaces

Abstract:
We consider the reduction of gauge theory on a four dimensional orientable manifold which is not a global product of two surfaces but contains embedded non-orientable surfaces. The resulting theory is a sigma-model on a two dimensional surface with boundary. We compare the discrete topological fluxes in four and two dimensional theories and verify the mirror symmetry as predicted by the S-duality in gauge theory. This provides another non-trivial test of S-duality.
