Résumé : We investigate a large class of supersymmetric magnetic brane solutions supported by U(1) gauge fields in AdS gauged supergravities. We obtain first-order equations in terms of a superpotential. In particular, we find systems which interpolate between AdSD-2 × Ω2 (where Ω2=S2 or H2) at the horizon and AdSD-type geometry in the asymptotic region, for 4≤D≤7. The boundary geometry of the AdSD-type metric is MinkowskiD-3×Ω2. This provides smooth supergravity solutions for which the boundary of the AdS spacetime compactifies spontaneously. These solutions indicate the existence of a large class of superconformal field theories in diverse dimensions whose renormalization group flow runs from the UV to the IR fixed-point. We show that the same set of first-order equations also admits solutions which are asymptotically AdSD-2 × Ω2 but singular at small distance. This implies that the stationary AdSD-2 × Ω2 solutions typically lie on the inflection points of the modulus space. © 2003 Elsevier B.V. All rights reserved.
