We consider field theories with sixteen supersymmetries, which includes U(N) Yang-Mills theories in various dimensions, and argue that their large N limit is related to certain supergravity… (More)

We construct three dimensional Chern-Simons-matter theories with gauge groups U(N)×U(N) and SU(N)×SU(N) which have explicit N = 6 superconformal symmetry. Using brane constructions we argue that the… (More)

We compute the three point correlation functions for primordial scalar and tensor fluctuations in single field inflationary models. We obtain explicit expressions in the slow roll limit where the… (More)

We find the gravity dual of a marginal deformation of N = 4 super Yang Mills, and discuss some of its properties. This deformation is intimately connected with an SL(2, R) symmetry of the gravity… (More)

We find the gravity solution corresponding to a large number of NS or D fivebranes wrapped on a two sphere so that we have pure N = 1 super Yang-Mills in the IR. The supergravity solution is smooth,… (More)

We review the holographic correspondence between "eld theories and string/M theory, focusing on the relation between compacti"cations of string/M theory on Anti-de Sitter spaces and conformal "eld… (More)

In the first part of this paper we find supergravity solutions corresponding to branes on worldvolumes of the form R × Σ where Σ is a Riemann surface. These theories arise when we wrap branes on… (More)

We investigate the embedding of brane inflation into stable compactifications of string theory. At first sight a warped compactification geometry seems to produce a naturally flat inflaton potential,… (More)

Studies of N = 4 super Yang Mills operators with large R-charge have shown that, in the planar limit, the problem of computing their dimensions can be viewed as a certain spin chain. These spin… (More)

We describe how to compute planar gluon scattering amplitudes at strong coupling in N = 4 super Yang Mills by using the gauge/string duality. The computation boils down to finding a certain classical… (More)
