We review the holographic correspondence between field theories and string/M theory,
focusing on the relation between compactifications of string/M theory on Anti-de Sitter …

We present the state of the art regarding the relation between the physics of Quantum Black
Holes and Noncommutative Geometry. We start with a review of models proposed in the …

It has been known for some time that the AdS/CFT correspondence predicts a limit on the
number of single particle states propagating on the compact spherical component of the …

A class of correlation functions of half-BPS composite operators are computed exactly (at
finite $ N $) in the zero coupling limit of N= 4 SYM theory. These have a simple dependence …

We investigate the “giant gravitons” of McGreevy, Susskind and Toumbas [1]. We
demonstrate that these are BPS configurations which preserve precisely the same …

Giant gravitons in AdS 5× S 5, and its orbifolds, have a dual field theory representation as
states created by chiral primary operators. We argue that these operators are not single …

The decoupling limit of the D1-D5 system compactified on T 4× S1 has a rich spectrum of U
(1) charged excitations. Even though these states are not BPS in the limit, BPS …

We review some aspects of the implementation of spacetime symmetries in noncommutative
field theories, emphasizing their origin in string theory and how they may be used to …

We study the SO (8) superconformal theory proposed recently by Bagger and Lambert as a
possible worldvolume theory for multiple M2-branes. For their explicit example with gauge …

We propose that the Euclidean bilocal collective field theory of critical large-N vector models
provides a complete definition of the proposed dual theory of higher spin fields in anti–de …
