Crossing symmetry in the H3+ WZNW model

Crossing Symmetry

The Quantum Superstring as a WZNW Model with N=2 Superconformal Symmetry

We present a new development in our approach to the covariant quantization of superstrings in 10 dimensions which is based on a gauged WZNW model. To incorporate worldsheet diffeomorphisms we need the quartet of ghosts (bzz, c , βzz, γ ) for topological gravity. The currents of this combined system form an N = 2 superconformal algebra. The model has vanishing central charge and contains two ant...

N = 2 Chiral Wznw Model in Superspace

We study the Poisson bracket algebra of the N = 2 supersymmetric chiral WZNW model in superspace. It involves two classical r-matrices, one of which comes from the geometrical constraints implied by N = 2 supersymmetry. The phase space itself consists of superfields satisfying constraints involving this r-matrix. An attempt is made to relax these constraints. The symmetries of the model are inv...

Equivalence of Chern-Simons gauge theory and WZNW model using a BRST symmetry

The equivalence between the Chern-Simons gauge theory on a threedimensional manifold with boundary and theWZNWmodel on the boundary is established in a simple and general way using the BRST symmetry. Our approach is based on restoring gauge invariance of the Chern-Simons theory in the presence of a boundary. This gives a correspondence to the WZNW model that does not require solving any constra...
