Abstract

We examine here discontinuities in the metric, the antisymmetric tensor and the dilaton field which are allowed by conformal invariance. We find that the surfaces of discontinuity must necessarily be null and both shock and impulsive waves are allowed. We employ our results for the case of colliding plane gravitational waves and we discuss the SL(2, [Formula: see text]) × SU(2)/[Formula: see text] × [Formula: see text]WZW model in the present perspective. In particular, the singularities encountered in this model may be viewed as the result of the mutual focusing of the colliding waves.
