Target-Space Duality in Heterotic and Type I Effective Lagrangians

Zygmunt Lalak, Stéphane Lavignac, Hans Peter Nilles

We study the implications of target-space duality symmetries for low-energy effective actions of various four-dimensional string theories. In the heterotic case such symmetries can…

Exact Solution of the Six-Vertex Model on a Random Lattice

Ivan Kostov

We solve exactly the 6-vertex model on a dynamical random lattice, using its representation as a large N matrix model. The model describes a gas of dense nonintersecting oriented l…

Supergravity Inspired Warped Compactifications and Effective Cosmological Constants

C. Grojean, J. Cline, G. Servant

We propose a supergravity inspired derivation of a Randall-Sundrum's type action as an effective description of the dynamics of a brane coupled to the bulk through gravity only. Th…

Boundary Conditions in Rational Conformal Field Theories

Roger E. Behrend, Paul A. Pearce, Valentina B. Petkova +1

We develop further the theory of Rational Conformal Field Theories (RCFTs) on a cylinder with specified boundary conditions emphasizing the role of a triplet of algebras: the Verli…

High energy scattering and the AdS/CFT correspondence

R. A. Janik, R. Peschanski

We consider small angle and large impact parameter high energy scattering of colourless states in SYM using the AdS/CFT correspondence. The gauge theory scattering amplitude is lin…

Integrable 2D Lorentzian Gravity and Random Walks

P. Di Francesco, E. Guitter, C. Kristjansen

We introduce and solve a family of discrete models of 2D Lorentzian gravity with higher curvature, which possess mutually commuting transfer matrices, and whose spectral parameter…

Dimensionally Reduced SYM_4 as Solvable Matrix Quantum Mechanics

Jens Hoppe, Vladimir Kazakov, Ivan K. Kostov

We study the quantum mechanical model obtained as a dimensional reduction of N=1 super Yang-Mills theory to a periodic light-cone "time". After mapping the theory to a cohomologica…

The Potts-q random matrix model : loop equations, critical exponents, and rational case

B. Eynard, G. Bonnet

In this article, we study the q-state Potts random matrix models extended to branched polymers, by the equations of motion method. We obtain a set of loop equations valid for any a…

Renormalization of gauge theories and master equation

Jean Zinn-Justin

The evolution of ideas which has led from the first proofs of the renormalizability of non-abelian gauge theories, based on Slavnov--Taylor identities, to the modern proof based on…

Solution of Potts-3 and Potts-\infty Matrix Models with the Equations of Motion Method

G. Bonnet

In this letter, we show how one can solve easily the Potts-3 + branching interactions and Potts-\infty matrix models, by the means of the equations of motion (loop equations). We g…

Super Fivebranes near the boundary of

C. Grojean, J. Mourad

We determine, to the first order in the radius of Anti-de-Sitter, the realisation of the superconformal algebra on vector fields. We then calculate, to this order, the…
