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 …

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 a variation of spacetime noncommutative field theory to realize the stringy
spacetime uncertainty relation without breaking any of the global symmetries of the …

We construct spherical harmonics for fuzzy spheres of even and odd dimensions,
generalizing the correspondence between finite Matrix algebras and fuzzy two-spheres. The …

We examine a family of BPS solutions of ten-dimensional type-IIB supergravity. These
solutions asymptotically approach AdS5× S5 and carry internal 'angular'momentum on the …

Enhanced global non-Abelian symmetries at zero coupling in Yang Mills theory play an
important role in diagonalizing the two-point functions of multimatrix operators. Generalized …

Certain correlation functions are computed exactly in the zero coupling limit of Script N= 4
super Yang-Mills theory with gauge group SU (N). A set of linearly independent operators …
