Ads/cft Dualities Involving Large 2d N=4 Superconformal Symmetry

چکیده
We study the duality between string theory on AdS3 × S × S and twodimensional conformal theories with large N = 4 superconformal algebra Aγ. We discuss configurations of intersecting branes which give rise to such near-horizon geometries. We compute the Kaluza-Klein spectrum and propose that the boundary superconformal theory can be described by a sigma model on a suitable symmetric product space with a particular choice of anti-symmetric two-form.

Large N Elliptic Genus and AdS / CFT Correspondence
According to one of Maldacena's dualities, type IIB string theory on AdS 3 × S 3 × K3 is equivalent to a certain N = (4, 4) superconformal field theory. In this note we compute the elliptic genus of the boundary theory in the su-pergravity approximation. A finite quantity is obtained once we introduce a particular exclusion principle. In the regime where the supergravity approximation is reliab...
متن کاملA holographic computation of the central charges of d = 4 , N = 2 SCFTs
We use the AdS/CFT correspondence to compute the central charges of the d = 4, N = 2 superconformal field theories arising from N D3-branes at singularities in F-theory. These include the conformal theories with En global symmetries. We compute the central charges a and c related to the conformal anomaly, and also the central charges k associated to the global symmetry in these theories. All of...

We consider families of theories with large N = 4 superconformal symmetry. We define an index generalizing the elliptic genus of theories with N = 2 symmetry. In contrast to the N = 2 case, the new index constrains part of the non-BPS spectrum. Motivated by aspects of the AdS/CFT correspondence we study the index in the examples of symmetric product theories. We give a physical interpretation o...
متن کاملClassical Hamiltonian Reduction On D ( 2 | 1 ; α ) Chern - Simons Gauge Theory and Large N = 4 Superconformal Symmetry
3d Chern-Simons gauge theory has a strong connection with 2d CFT and link invariants in knot theory. We impose some constraints on the D(2|1;α) CS theory in the similar context of the hamiltonian reduction of 2d superconformal algebras. There Hilbert states in D(2|1;α) CS theory are partly identified with characters of the large N = 4 SCFT by their transformation properties. e-mail: ishimoto@ph...
