We review recent developments (up to January 2004) of the Liouville field theory and its
matrix model dual. This review consists of two parts. In part I, we review the bosonic Liouville …

This is a brief review of the current state of knowledge onlittle string theories', which are non-
gravitational theories having several string-like properties. We focus on the six-dimensional …

A bstract It was recently shown that the theory obtained by deforming a general two
dimensional conformal theory by the irrelevant operator\(T\overline {T}\) is solvable. In the …

A bstract We study families of two dimensional quantum field theories, labeled by a
dimensionful parameter μ, that contain a holomorphic conserved U (1) current J (z). We …

A bstract Recently we proposed a universal solvable irrelevant deformation of AdS 3/CFT 2
duality, which leads in the ultraviolet to a theory with a Hagedorn entropy [1]. In this note we …

A bstract We revisit the minimal tension (k= 1) string theory on AdS 3× S 3× 𝕋 4. We propose
a new free-field description of the worldsheet theory and show how localization of string …

We continue our study of string theory in a background that interpolates between A d S 3 in
the infrared and a linear dilaton spacetime R 1, 1× R ϕ in the UV. This background …

We calculate the spectrum of a two dimensional CFT on a cylinder, perturbed by a general
linear combination of, and, by utilizing the relation of this problem to certain solvable single …

A bstract We propose a new AdS 3/CFT 2 duality, in which the bulk string theory has a target
spacetime AdS 3 times a squashed three-sphere\({\mathbbm {S}} _ {\flat}^ 3\), and the dual …

A bstract We study two dimensional conformal field theory with a left-moving conserved
current J, perturbed by an irrelevant, Lorentz symmetry breaking operator with the quantum …
