Orbifolds of AdS3 and fixpoints of the CFT
نویسنده
چکیده
The 3-d BTZ black hole represents an orbifold of AdS3 gravity. The UV as well as the IR region of the CFT is governed by a gauged SL(2,R) WZW model. In the UV it corresponds to a light-cone gauging (Liouville model) whereas in the IR it is a space-like gauging (2-d black hole).

Exciting AdS Orbifolds
The supersymmetric (AdS3×S)/ZN orbifold constructed by the authors in hep-th/0106171 is shown to describe AdS fragmentation, where fivebranes are emerging from the F1-NS5 background. The twisted sector moduli of the orbifold are the collective coordinates of groups of n5/N fivebranes. We discuss the relation between the descriptions of this background as a perturbative string orbifold and as a ...
متن کاملD-branes in Lorentzian AdS3
We study the exact construction of D-branes in Lorentzian AdS3. We start by defining a family of conformal field theories that gives a natural Euclidean version of the SL(2,R) CFT and does not correspond to H3 , the analytic continuation of AdS3. We argue that one can recuperate the exact CFT results of Lorentzian AdS3, upon an analytic continuation in the moduli space of these conformal field ...
متن کاملTwo Dimensional Anti-de Sitter Space and Discrete Light Cone Quantization
We realize the two dimensional anti-de Sitter (AdS2) space as a KaluzaKlein reduction of the AdS3 space in the framework of the discrete light cone quantization (DLCQ). Introducing DLCQ coordinates which interpolate the original (unboosted) coordinates and the light cone coordinates, we discuss that AdS2/CFT correspondence can be deduced from the AdS3/CFT . In particular, we elaborate on the de...
متن کاملSuperstring Theory on AdS 3 × G / H and Boundary N = 3 Superconformal Symmetry
Superstrings propagating on backgrounds of the form AdS3 ×G/H are studied using the coset CFT approach. We focus on seven dimensional cosets which have a semiclassical limit, and which give rise to N = 3 superconformal symmetry in the dual CFT. This is realized for the two cases AdS3 × SU(3)/U(1) and AdS3 × SO(5)/SO(3), for which we present an explicit construction. We also provide sufficient c...
متن کاملLodged in the throat: Internal infinities and AdS/CFT
In the context of AdS3/CFT2, we address spacetimes with a certain sort of internal infinity as typified by the extreme BTZ black hole. The internal infinity is a null circle lying at the end of the black hole’s infinite throat. We argue that such spacetimes may be described by a product CFT of the form CFTL⊗CFTR, where CFTR is associated with the asymptotically AdS boundary while CFTL is associ...
