Two-Dimensional Models With (0,2) Supersymmetry: Perturbative Aspects
Edward Witten
Certain perturbative aspects of two-dimensional sigma models with (0,2) supersymmetry are investigated. The main goal is to understand in physical terms how the mathematical theory…
SL(2,Z) Action On Three-Dimensional Conformal Field Theories With Abelian Symmetry
Edward Witten
On the space of three-dimensional conformal field theories with U(1) symmetry and a chosen coupling to a background gauge field, there is a natural action of the group $SL(2,{\bf Z…
Chiral Ring Of Sp(N) And SO(N) Supersymmetric Gauge Theory In Four Dimensions
Edward Witten
The chiral ring of classical supersymmetric Yang-Mills theory with gauge group or SO(N) is computed, extending previous work (of Cachazo, Douglas, Seiberg, and the author)…
Comments On String Theory
Edward Witten
String theory avoids the ultraviolet infinities that arise in trying to quantize gravity. It is also more predictive than conventional quantum field theory, one aspect of this bein…
Singularities in string theory
Edward Witten
String theory is a quantum theory that reproduces the results of General Relativity at long distances but is completely different at short distances. Mathematically, string theory…
Multi-Trace Operators, Boundary Conditions, And AdS/CFT Correspondence
Edward Witten
We argue that multi-trace interactions in quantum field theory on the boundary of AdS space can be incorporated in the AdS/CFT correspondence by using a more general boundary condi…
