Description
We obtain a complete classification of the half-supersymmetric branes
of IIA/IIB string theory compactified on tori based on non-perturbative
dualities. Many of these branes are `exotic', in the sense that they do
not arise from the dimensional reduction of branes in ten dimensions. We
then consider a specific N=1 model in four dimensions with fluxes turned
on, and we determine the subset of the space-filling 3-branes of the
maximal theory that are not projected out in the model. We point out
that all such branes can simultaneously be included to cancel the
tadpoles induced by the fluxes, giving in principle many new solutions
to the consistency conditions that these fluxes must satisfy.
