un 1 99 8 S 3 × S 3 acts freely on S 3 × S 3
A free action of the direct product of two copies of the symmetric group on 3 elements on the cartesian product of two copies of the 3-sphere is constructed. This nonlinear action is constructed using surgery. The action provides a counterexample to a conjecture of Lewis made in 1968. Results of P. A. Smith [10] and J. Milnor [5] show that a dihedral group cannot act freely on a sphere. This im...

متن کاملSearch 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...
متن کاملThe 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.
متن کاملAdS 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...
