AdS pp - waves
نویسنده
چکیده
We obtain the pp-waves of D = 5 and D = 4 gauged supergravities supported by U (1) 3 and U (1) 4 gauged field strengths respectively. We show that generically these solutions preserve 1/4 of the supersymmetry, but supernumerary supersymmetry can arise for appropriately constrained harmonic functions associated with the pp-waves. In particular it implies that the solutions are independent of the light-cone coordinate x +. We also obtain the pp-waves in the Freedman-Schwarz model.

PP - waves in AdS Gauged Supergravities and Supernumerary Supersymmetry
Purely gravitational pp-waves in AdS backgrounds are described by the generalised Kaigorodov metrics, and they generically preserve 1 4 of the maximum supersymmetry allowed by the AdS spacetimes. We obtain 1 2 supersymmetric purely gravitational pp-wave solutions, in which the Kaigorodov component is set to zero. We construct pp-waves in AdS gauged supergravities supported by a vector field. We...

Purely gravitational pp-waves in AdS backgrounds are described by the generalised Kaigorodov metrics, and they preserve 1 4 of the maximum supersymmetry allowed by the AdS spacetimes. We construct pp-waves in gauged AdS supergravities supported by a field strength. We find that the solutions in D = 4 and D = 5 can then preserve 1 2 of the supersymmetry. Like those in ungauged supergravities, th...

Purely gravitational pp-waves in AdS backgrounds are described by the generalised Kaig-orodov metrics, and they generically preserve 1 4 of the maximum supersymmetry allowed by the AdS spacetimes. We obtain 1 2 supersymmetric purely-gravitional pp-wave solutions, in which the Kaigorodov component is set to zero. We construct pp-waves in AdS gauged su-pergravities supported by a vector field.

متن کاملMany Faces of D-branes: from Flat Space, via Ads to Pp-waves
We review recent studies of branes in AdS × S and pp-wave spaces using effective action methods (probe branes and supergravity). We also summarise results on an algebraic study of D-branes in these spaces, using extensions of the superisometry algebras which include brane charges.
متن کاملBranes, Waves and AdS Orbifolds
The embedding of a Taub-NUT space in the directions transverse to the world volume of branes describes branes at (spherical) orbifold singularities. Similarly, the embedding of a pp-wave in the brane world volume yields an AdS orbifold. In case of the D1-D5–brane system, the AdS3 orbifolds yields a BTZ black hole; as we will show, the same holds for D3–branes corresponding to AdS5. In addition ...
