Non-Abelian Duality in the String Effective Action | | A. Bossard

7 Aug 2000 | | Journal: | Nucl.Phys. B595 (2001) 93-118 | | Subject: | hep-th | | Affiliation: | U. of Tours), N. Mohammedi (U. of Tours | | Abstract: | We study the symmetry of the one-loop effective action of bosonic string theory under non-Abelian T-duality transformations. It is shown that the original Lagrangian and its dual are proportional. This result implies that the corresponding reduced low energy effective actions are equivalent and leads to a functional relation between the Weyl anomaly coefficients of the original and dual two-dimensional non-linear sigma models. {}Finally, we apply this formalism to some simple examples. | | Source: | arXiv, hep-th/0008062 | | Services: | Forum | Review | PDF | Favorites | |
