Journal ArticleDOI
Gauge Theory Correlators from Non-Critical String Theory
TL;DR: In this paper, a boundary of the anti-deSitter space analogous to a cut-off on the Liouville coordinate of the two-dimensional string theory is introduced to obtain certain Green's functions in 3+1-dimensional N = 4 supersymmetric Yang-Mills theory with a large number of colors via non-critical string theory.
Journal ArticleDOI
Supergravity and a confining gauge theory: duality cascades and χSB-resolution of naked singularities
TL;DR: In this article, a non-singular pure-supergravity background dual to the field theory on all scales, with small curvature everywhere if the ‘t Hooft coupling gsM is large, was proposed.
Journal ArticleDOI
Ads/CFT correspondence and symmetry breaking
Igor R. Klebanov,Edward Witten +1 more
TL;DR: In this paper, the authors study the vacua of field theories where some of the gauge symmetry is broken by expectation values of scalar fields, and show how to calculate them from the behavior of perturbations to the AdS background near the boundary.
Journal ArticleDOI
Superconformal field theory on threebranes at a Calabi-Yau singularity
Igor R. Klebanov,Edward Witten +1 more
TL;DR: In this paper, it was shown that string theory on AdS5 × X5 can be described by a certain N = 1 supersymmetric gauge theory, which we describe in detail.
Journal ArticleDOI
A semi-classical limit of the gauge/string correspondence
TL;DR: In this article, a world-sheet sigma model is applied to string theories dual to four-dimensional gauge theories, and semi-classical soliton solutions representing highly excited string states are identified which correspond to gauge theory operators with relatively small anomalous dimensions.
