Bps Black Holes in Gauged N=4, D=4 Supergravity Typeset Using Revt E X 2
We find solutions of the bosonic sector of gauged N=4, D=4 SU(2) × SU(2) supergravity, which represent dilaton black holes with toroidal or spherical event horizons. The axion is consistently truncated, and the gauge group is broken to U(1) × U(1). The spherical black holes carry two electric and two magnetic abelian charges, whereas the toroidal holes have vanishing magnetic charges. The space...
متن کاملD-instantons and Black Holes in N=2, D=4 Supergravity
We discuss T-duality between the solutions of type II A versus type II B superstrings compactiied on Calabi-Yau threefolds. Within the context of N = 2, D = 4 supergravity eeective Lagrangian, the T-duality transformation is equivalently described by the c-map, which transforms the IIA black hole solutions into the IIB D-instanton solutions. We construct via this mapping a broad class of D-inst...
متن کاملNon-Abelian BPS Monopoles in N=4 Gauged Supergravity
We study static, spherically symmetric, and purely magnetic solutions of SU(2) × SU(2) gauge supergravity in four dimensions. A systematic analysis of the supersymmetry conditions reveals solutions which preserve 1/8 of the supersymmetries and are characterized by a BPS-monopole-type gauge field and a globally hyperbolic, everywhere regular geometry. These present the first known example of non...
متن کاملGauged N=4 Supergravity through Compactification and BPS Monopoles
It is shown that N=4 gauged supergravity in four dimensions is obtained by compactifying N=1 supergravity in ten dimensions on the group manifold S × S. This could be further related to supergravity in eleven dimensions. Analysis of supersymmetry conditions of N=4 gauged supergravity in four dimensions reveals solutions which preserve 1/4 of the supersymmetries and are characterized by a BPS-mo...
متن کامل/4 Bps Solutions in Massive Iia Supergravity
We study four kinds of 1/4 BPS solutions in massive IIA supergravity corresponding to D8-D0-F1, D8-D2, D8-D4 and D8-D6-NS5 systems. We show that these solutions are reproduced without making nontrivial assumptions by using supersymmetry conditions. D8D2 and D8-D4 solutions are represented by harmonic functions, as usual, while the other two are represented by solutions of non-linear differentia...
