By promoting an invariant subgroup H of ISO (2,1) to a gauge symmetry of a WZWN action, we obtain the description of a bosonic string moving either in a curved 4-dimensional space-time with an axion field and curvature singularities or in 3-dimensional Minkowski space-time.

Abstract
By promoting an invariant subgroup H of ISO (2,1) to a gauge symmetry of a WZWN action, we obtain the description of a bosonic string moving either in a curved 4-dimensional space-time with an axion field and curvature singularities or in 3-dimensional Minkowski space-time.File in questo prodotto:
