  This research announcement gives a brief report of the main results in our
paper "PU(2) monopoles, I: Regularity, Uhlenbeck compactness, and
transversality" (Journal of Differential Geometry, to appear). We describe the
existence of perturbations for the PU(2) monopole equations, yielding both
useful transversality properties and an Uhlenbeck compactification for this
perturbed moduli space.
