Semiclassical strings in AdS 3 × S 2

In this paper, we investigate the semiclassical strings in AdS3×S, in which the string configuration of AdS3 is classified to three cases depending on the parameters. Each of these has a different anomalous dimension proportional to log S, S1/3 and S, where S is a angular momentum on AdS3. Further we generalize the dispersion relations for various string configuration on AdS3 × S.

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...

The holographic dual of AdS 3 × S 3 × S 3 × S 1

We construct the two dimensional N = (0, 4) gauge theory that lives on the world volume of D1-branes and intersecting D5-branes. We conjecture that this theory flows in the infra-red to a fixed point with large N = (4, 4) superconformal symmetry. The central charge of the conformal field theory is shown to coincide with the holographic dual of string theory compactified on AdS3 × S × S × S.

AdS 3 × w ( S 3 × S 3 × S 1 ) Solutions of Type IIB String Theory

We analyse a recently constructed class of local solutions of type IIB supergravity that consist of a warped product of AdS3 with a sevendimensional internal space. In one duality frame the only other nonvanishing fields are the NS three-form and the dilaton. We analyse in detail how these local solutions can be extended to globally well-defined solutions of type IIB string theory, with the int...
