We construct a conformal field theory dual to string theory on AdS 3 with pure NS–NS flux. It
is given by a symmetric orbifold of a linear dilaton theory deformed by a marginal operator …

A bstract We examine the question how string theory achieves a sum over bulk geometries
with fixed asymptotic boundary conditions. We discuss this problem with the help of the …

We discuss in detail the 1+ 1-dimensional superconformal field theory dual to type II string
theory on AdS 3× S 3× T 4, emphasizing the string theoretic aspects of this duality. For one …

We propose a worldsheet description for the AdS 5× S 5 string theory dual to large N, free
N= 4 supersymmetric Yang-Mills theory in four dimensions. The worldsheet theory is a …

The BPS sector in A d S 3/CFT 2 AdS_3/CFT_2 duality has been fertile ground for the
exploration of gauge/gravity duality, from the match between black hole entropy and the CFT …

A bstract The worldsheet string theory dual to free 4d\(\mathcal {N}\)= 4 super Yang-Mills
theory was recently proposed in [1]. It is described by a free field sigma model on the twistor …

A bstract Given an asymptotically Anti-de Sitter supergravity solution, one can obtain a
microscopic interpretation by identifying the corresponding state in the holographically dual …

A bstract We revisit the computation of string worldsheet correlators on Euclidean AdS 3 with
pure NS-NS background. We compute correlation functions with insertions of spectrally …

A bstract The determination of the string vertices of closed string field theory is shown to be a
conformal field theory problem solvable by combining insights from Liouville theory …

A bstract The symmetric orbifold of 𝕋 4 is exactly dual to string theory on AdS 3× S 3× 𝕋 4
with minimal (k= 1) NS-NS flux. In this paper we study the perturbation of the symmetric …
