Recently, there has been much investigation of the dynamics of three-dimensional supersymmetric gauge theories with N = 4 supersymmetry, Two of the most remarkable discoveries are as follows. i) In some cases, the Coulomb branch of vacua is isomorphic, as a hyper-K~ihler manifold, to a moduli space of three-dimensional monopole solutions in a different gauge theory. For instance, the three-dimensional theory with SU(k) gauge theory and no hypermultiplets has for its Coulomb branch the moduli space of k-monopole configurations of an SU(2) gauge theory in 3 + I dimensions. (This was shown in \[ 1 \] tbr k = 2; the generalization to higher k was proposed in \[2\].) E-mail: [email protected] Research supported in part by NSF Grant PHY-9513835. E-mail: winen@ ias.edu

N2 - We propose an explanation via string theory of the correspondence between the Coulomb branch of certain three-dimensional supersymmetric gauge theories and certain moduli spaces of magnetic monopoles. The same construction also gives an explanation, via SL(2, ℤ) duality of Type IIB superstrings, of the recently discovered "mirror symmetry" in three dimensions. New phase transitions in three dimensions as well as new infrared fixed points and even new coupling constants not present in the known Lagrangians are predicted from the string theory construction. An important role in the construction is played by a novel aspect of brane dynamics in which a third brane is created when two branes cross.
