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…
A Note On The Chern-Simons And Kodama Wavefunctions
Edward Witten
Yang-Mills theory in four dimensions formally admits an exact Chern-Simons wavefunction. It is an eigenfunction of the quantum Hamiltonian with zero energy. It is known to be unphy…
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…
