This generalizes the original DFT that was derived via expanding closed string field theory on a torus up to cubic order. The action and gauge transformations are derived for fluctuations around the generalized group manifold background up to cubic order, revealing the appearance of a generalized Lie derivative and a corresponding C-bracket upon invoking a new version of the strong constraint. In all these quantities a background dependent covariant derivative appears reducing to the partial derivative for a toroidal background. This approach sheds some new light on the conceptual status of DFT, its background (in-)dependence and the up-lift of non-geometric Scherk-Schwarz reductions.", "revisions": [ { "version": "v1", "updated": "2014-10-23T14:23:36.000Z" } ], "analyses": { "keywords": [ "double field theory", "group manifold", "closed string field theory", "general left-right asymmetric wzw model", "covariant derivative appears reducing" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/JHEP02(2015)001", "journal": "Journal of High Energy Physics", "year": 2015, "month": "Feb", "volume": 2015, "pages": 1 }, "note": { "typesetting": "TeX", "pages": 43, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1323484, "adsabs": "2015JHEP...02..001B" } } }
