Solution of the SL(2,R) string in curved spacetime
Itzhak Bars
The SL(2,R) WZW model, one of the simplest models for strings propagating in curved space time, was believed to be non-unitary in the algebraic treatment involving affine current a…

Ghost-Free Spectrum of a Quantum String in SL(2,R) Curved Spacetime
Itzhak Bars
The unitarity problem in curved spacetime is solved for the string described by the SL(2,R) WZW model. The spectrum is computed exactly and demonstratedto be ghost-free. The new fe…
