NON-ABELIAN SOLITONS IN N=4 GAUGED SUPERGRAVITY AND LEADING ORDER STRING THEORY

We study static, spherically symmetric, and purely magnetic solutions of the N=4 gauged supergravity in four dimensions. A systematic analys is of the supersymmetry conditions reveals solutions which preserve 1/ 4 of the supersymmetries and are characterized by a BPS-monopole-type gauge field and a globally hyperbolic, everywhere regular geometry. We show that the theory in which these solutions arise can be obtained v ia compactification of ten-dimensional supergravity on the group manif old. This result is then used to lift the solutions to ten dimensions.
