AdS3 × R as a target space for the (2, 1) string theory Original Research Article

We study a target space geometry of the form AdS3 × R for the (2, 1) heterotic string. This target space arises as the near horizon limit of a solitonic configuration in 2 + 2 dimensions. We investigate the null isometries of this space and discuss the specific reduction to 1 + 1 dimensions of the target space geometry arising from the consistent gauging of one of these isometries.
