| Popis | Poisson-Lie duality is a generalization of Abelian and non-Abelian T duality, and it can be viewed as a map between solutions of the low-energy effective equations of string theory, i.e., at the (super) gravity level. We show that this fact extends to the next order in alpha' (two loops in sigma-model perturbation theory) provided that the map is corrected. The alpha' correction to the map is induced by the anomalous Lorentz transformations of the fields that are necessary to go from a doubled O(D, D)-covariant formulation to the usual (super)gravity description. |
