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 non-critical… (More)

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 relevantN = 1 SUSY… (More)

Just as parallel threebranes on a smooth manifold are related to string theory on AdS5 × S, parallel threebranes near a conical singularity are related to string theory on AdS5 × X5, for a suitable… (More)

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… (More)

A world-sheet sigma model approach is applied to string theories dual to fourdimensional gauge theories, and semi-classical soliton solutions representing highly excited string states are identified… (More)

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 the… (More)

We consider unstable D0-branes of two dimensional string theory, described by the boundary state of Zamolodchikov and Zamolodchikov [hepth/0101152] multiplied by the Neumann boundary state for the… (More)

We consider the type 0 theories, obtained from the closed NSR string by a diagonal GSO projection which excludes space-time fermions, and introduce D-branes into these theories. The low-energy… (More)

We calculate classical cross sections for absorption of massless scalars by the extremal 3branes of type IIB theory, and by the extremal 2and 5-branes of M-theory. The results are compared with… (More)
