Abstract
We consider gauged WZW models based on a four dimensional non-semi-sim ple group. We obtain conformal sigma-models in D = 3 spacetime dimensi ons (with exact central charge c = 3) by axially and vectorially gaugi ng a one-dimensional subgroup. The model obtained in the axial gauging is related to the 3D black string after a correlated limit is taken i n the latter model. By identifying the CFT corresponding to these sigm a-models we compute the exact expressions for the metric and dilaton f ields. All of our models can be mapped to flat spacetimes with zero an tisymmetric tensor and dilaton fields via duality transformations.
