WZNW Strings, Unitarity and Anti de Sitter spaces
Jonas Bjornsson, Stephen Hwang
We investigate the unitarity of strings on non-trivial space-time backgrounds based on gauged WZNW models involving SO(n,2), gauging an SO(n,1) subgroup. As geometric coset spaces,…
Gauged non-compact WZNW models, revisited
Jonas Bjornsson, Stephen Hwang
The purpose of the present paper is to investigate the necessary conditions for unitarity of the spectrum of non-compact gauged WZNW models to some depth. In particular, we would l…
CFT description of three-dimensional Kerr-de Sitter spacetime
Jens Fjelstad, Stephen Hwang, Teresia Mansson
We describe three-dimensional Kerr-de Sitter space using similar methods as recently applied to the BTZ black hole. A rigorous form of the classical connection between gravity in t…
Logarithmic Conformal Field Theories via Logarithmic Deformations
J. Fjelstad, J. Fuchs, S. Hwang +2
We construct logarithmic conformal field theories starting from an ordinary conformal field theory -- with a chiral algebra C and the corresponding space of states V -- via a two-s…
Sectors of solutions in three-dimensional gravity and Black Holes
Jens Fjelstad, Stephen Hwang
We examine the connection between three dimensional gravity with negative cosmological constant and two-dimensional CFT via the Chern-Simons formulation. A set of generalized spect…
Equivalence of Chern-Simons gauge theory and WZNW model using a BRST symmetry
Jens Fjelstad, Stephen Hwang
The equivalence between the Chern-Simons gauge theory on a three-dimensional manifold with boundary and the WZNW model on the boundary is established in a simple and general way us…
