چکیده

We show the existence of an infinite set of non-local classically conserved charges on the Green-Schwarz closed superstring in a pp-wave background. We find that these charges agree with the Penrose limit of non-local classically conserved charges recently found for the AdS5 × S Green-Schwarz superstring. The charges constructed in this paper could help to understand the role played by these on the full AdS5 × S background.

Many 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.

Quantum Consistency of the Superstring in AdS 5 × S 5 Background

Using arguments based on BRST cohomology, the pure spinor formalism for the su-perstring in an AdS 5 × S 5 background is proven to be BRST invariant and conformally invariant at the quantum level to all orders in perturbation theory. Cohomology arguments are also used to prove the existence of an infinite set of non-local BRST-invariant charges at the quantum level.

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...

PP - waves in AdS Gauged Supergravities and Supernumerary

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...
