Název v původním jazyce

Plane-parallel waves as duals of the flat background III: T-duality with torsionless B-field

Popis výsledku v původním jazyce

By addition of non-zero, but torsionless B -field, we expand the classification of (non-)Abelian T-duals of the flat background in four dimensions with respect to 1, 2, 3 and 4D subgroups of the Poincaré group. We discuss the influence of the additional B -field on the process of dualization, and identify essential parts of the torsionless B -field that cannot in general be eliminated by coordinate or gauge transformation of the dual background. These effects are demonstrated using particular examples. Due to their physical importance, we focus on duals whose metrics represent plane-parallel (pp-)waves. Besides the previously found metrics, we find new pp-waves depending on parameters originating from the torsionless B -field. These pp-waves are brought into their standard forms in Brinkmann and Rosen coordinates.
