Superstring Theory on AdS 3 × G / H and Boundary N = 3 Superconformal Symmetry
نویسنده
چکیده
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 conditions on a CFT background to enable a similar construction, and comment on the geometrical interpretation of our results.

Supersymmetric string vacua on AdS3 ×N
String backgrounds of the form AdS 3 × N that give rise to two dimensional spacetime superconformal symmetry are constructed. 1. Introduction In this letter we study the conditions on curved string backgrounds of the form AdS 3 × N that give rise to spacetime superconformal symmetry. We use the NSR formulation; for simplicity we describe the left moving sector only – it can be combined with the...

We study superstring theories on AdS3 × N backgrounds yielding N = 2, 3, 4 extended superconformal symmetries in the dual boundary CFT. In each case the necessary constraints on the internal worldsheet theory N are found.
متن کاملGreen-Schwarz Superstrings on AdS3 and the Boundary N = 4 Superconformal Algebra
We study the hybrid formulation of Green-Schwarz superstrings on AdS3 with NS flux and the boundary N = 4 superconformal algebra. We show the equivalence between the NSR and GS superstrings by a field redefinition. The boundary N = 4 superconformal algebra is realized by the free fields of the affine Lie superalgebra A(1|1)(1). We also consider the light-cone gauge and obtain the N = 4 superLio...

We demonstrate how actions for interacting superconformal field theories in (p+1)-dimensions arise as a result of gauge fixing worldvolume diffeomorphisms and fermionic κ-symmetry in actions for super-p-branes propagating in superbackgrounds of AdSp+2×S geometry. The method of nonlinear realizations and coset spaces is used for getting an explicit form of supervielbeins and superconnections of ...
متن کاملHarmonic Analysis and Superconformal Gauge Theories in Three Dimensions from AdS/CFT Correspondence
In this thesis I review various aspects of the AdS4/CFT3 correspondence, where AdS4 supergravity arises from compactification of M–theory on a coset space G/H and preserves N < 8 supersymmetries. One focal point of my review is that the complete spectrum of such N–extended supergravity can be determined by means of harmonic analysis on the homogeneous space G/H. This spectrum can be matched wit...
