We show that the constructions in string theory of the (geometrical) $T$-duality with $H$-fluxes for principle bundles naturally arise as reductions of factorizable Poisson Lie group actions. In particular, the group may be non-abelian.", "revisions": [ { "version": "v3", "updated": "2006-11-14T19:55:18.000Z" } ], "analyses": { "subjects": [ "53C15", "53D20" ], "keywords": [ "generalized geometry", "factorizable poisson lie group actions", "principle bundles", "generalized complex structure", "hamiltonian action" ], "note": { "typesetting": "LaTeX", "pages": 23, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math.....12634H" } } }
