Quantum corrections to short folded superstring in AdS 3 × S 3 × M 4

Born - Infeld Corrections to D 3 Brane Action in AdS 5 × S 5 and N = 4 , d = 4 Primary

We consider certain supersymmetric Born-Infeld couplings to the D3 brane action and show that they give rise to massless and massive KK excitations of type IIB on AdS5×S5, in terms of primary singleton Yang-Mills superfields. ∗Work supported in part by the EEC under TMR contract ERBFMRX-CT960090, ECC Science Program SCI∗ -CI92-0789 (INFN-Frascati), DOE grant DE-FG0391ER40662 and CONICIT fellowship

Quantum Consistency of the Superstring in AdS 5 × S 5

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.

Search for a holographic dual to AdS 3 × S 3 × S 3 × S 1

The problem of finding a holographic dual to string theory on AdS3 × S × S3 × S1 is examined in depth. This background supports a large N = 4 superconformal symmetry. While in some respects similar to the familiar small N = 4 systems on AdS3 × S3 ×K3 and AdS3 × S3 × T 4, there are important qualitative differences. Using an analogue of the elliptic genus for large N = 4 theories we rule out all...
