**public sources and our publisher partners.**Abstract We suggest a means of obtaining 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. The… Expand

We revisit the singular IIB supergravity solution describing M fractional 3branes on the conifold [hep-th/0002159]. Its 5-form flux decreases, which we explain by showing that the relevant N = 1 SUSY… Expand

Just as parallel threebranes on a smooth manifold are related to string theory on AdS5 × S5, parallel threebranes near a conical singularity are related to string theory on AdS5 × X5, for a suitable… Expand

Abstract A world-sheet sigma model approach is applied to string theories dual to four-dimensional gauge theories, and semi-classical soliton solutions representing highly excited string states are… Expand

Abstract We study, using the dual AdS description, the vacua of field theories where some of the gauge symmetry is broken by expectation values of scalar fields. In such vacua, operators built out of… Expand

The world volume theory on N regular and M fractional D3-branes at the conifold singularity is a non-conformal N=1 supersymmetric SU(N+M)×SU(N) gauge theory. In previous work the Type IIB… Expand

For 3-dimensional field theories with $ \mathcal{N} = 2 $ supersymmetry the Euclidean path integrals on the three-sphere can be calculated using the method of localization; they reduce to certain… Expand

We suggest a general relation between theories of infinite number of higher-spin massless gauge fields in AdSd+1 and large N conformal theories in d dimensions containing N-component vector fields.… Expand

Abstract We investigate the entanglement entropy in gravity duals of confining large N c gauge theories using the proposal of [S. Ryu, T. Takayanagi, Phys. Rev. Lett. 96 (2006) 181602, hep-th/0603001… Expand

We consider two dimensional supergravity coupled to $\hat c=1$ matter. This system can also be interpreted as noncritical type 0 string theory in a two dimensional target space. After reviewing and… Expand
