Little string theory in a double scaling limit
A double scaling limit can be defined in string theory on a Calabi-Yau (CY) manifold by approaching a point in moduli space where the CY space develops an isolated singularity and at the same timeExpand

Comments on string theory on AdS(3)
We study string propagation on $AdS_3$ times a compact space from an ``old fashioned'' worldsheet point of view of perturbative string theory. We derive the spacetime CFT and its Virasoro and currentExpand

Seiberg duality in Chern–Simons theory
Abstract We argue that N = 2 supersymmetric Chern–Simons theories exhibit a strong–weak coupling Seiberg-type duality. We also discuss supersymmetry breaking in these theories.

Branes and N = 1 duality in string theory
Abstract We propose a construction of dual pairs in four dimensional N = 1 supersymmetric Yang-Mills theory using branes in type IIA string theory.

Journal of High Energy Physics Little string theory at a TeV
We propose a framework where the string scale as well as all compact dimensions are at the electroweak scale ∼ TeV−1. The weakness of gravity is attributed to the small value of the string couplingExpand

Brane dynamics and N = 1 supersymmetric gauge theory
Abstract We discuss some aspects of the relation between space-time properties of branes in string theory, and the gauge theory on their world-volume, for models invariant under four supercharges inExpand

Brane dynamics and gauge theory
The authors review some aspects of the interplay between the dynamics of branes in string theory and the classical and quantum physics of gauge theories with different numbers of supersymmetries inExpand

Superstrings on AdS_3 and Symmetric Products
Some properties of N=2 superstrings on AdS_3 x N are studied. Their spectrum has the same pattern as 2-d CFTs in the moduli space of symmetric products M^p/S_p, where p is associated with the numberExpand

Holography for non-critical superstrings
We argue that a class of ``non-critical superstring'' vacua is holographically related to the (non-gravitational) theory obtained by studying string theory on a singular Calabi-Yau manifold in theExpand
