On the holographic renormalization group
We propose a direct correspondence between the classical evolution equations of $5-d$ supergravity and the renormalization group (RG) equations of the dual $4-d$ large $N$ gauge theory. UsingExpand
Six-dimensional supergravity on S3 × AdS3 and 2d conformal field theory
In this paper we study the relation between six-dimensional supergravity compactified on S 3 × AdS3 and certain two-dimensional conformal field theories. We compute the Kaluza-Klein spectrum ofExpand

Mass, entropy and holography in asymptotically de Sitter spaces
We propose a novel prescription for computing the boundary stress tensor and charges of asymptotically de Sitter (dS) spacetimes from data at early or late time infinity. If there is a holographicExpand
Permeable conformal walls and holography
We study conformal field theories in two dimensions separated by domain walls, which preserve at least one Virasoro algebra. We develop tools to study such domain walls, extending and clarifying theExpand
Exotic branes and nongeometric backgrounds
When string or M theory is compactified to lower dimensions, the U-duality symmetry predicts so-called exotic branes whose higher-dimensional origin cannot be explained by the standard string orExpand
Exotic Branes in String Theory
Abstract Besides the familiar D-branes, string theory contains a vast number of other non-perturbative objects. While a complete classification is lacking, many of these objects are related to eachExpand
Dynamics of N=2 supersymmetric gauge theories in three-dimensions
We study the structure of the moduli spaces of vacua and superpotentials of N = 2 supersymmetric gauge theories in three dimensions. By analyzing the instanton corrections, we compute the exactExpand
Mirror Symmetry in Three-Dimensional Gauge Theories, Quivers and D-Branes
We construct and analyze dual N = 4 supersymmetric gauge theories in three dimensions with unitary and symplectic gauge groups. The gauge groups and the field content of the theories are encoded inExpand
Brownian Motion in AdS/CFT
We study Brownian motion and the associated Langevin equation in AdS/CFT. The Brownian particle is realized in the bulk spacetime as a probe fundamental string in an asymptotically AdS black holeExpand
