Generalised T-Duality and Non-Geometric Backgrounds
We undertake a systematic analysis of non-geometric backgrounds in string theory by seeking stringy liftings of a class of gauged supergravity theories. In addition to conventional flux compactifications and non-geometric T-folds with T-duality transition functions, we find a new class of non-geometric backgrounds with non-trivial dependence on the dual coordinates that are conjugate to the str...
متن کاملT-duality, Non-geometry and Lie Algebroids in Heterotic Double Field Theory
A number of issues in heterotic double field theory are studied. This includes the analysis of the T-dual configurations of a flat constant gauge flux background, which turn out to be non-geometric. Performing a field redefinition to a nongeometric frame, these T-duals take a very simple form reminiscent of the constant Qand R-flux backgrounds. In addition, it is shown how the analysis of arXiv...
متن کاملT-duality, Quotients and Currents for Non-Geometric Closed Strings
We use the canonical description of T-duality as well as the formulation of T-duality in terms of chiral currents to investigate the geometric and non-geometric faces of closed string backgrounds originating from principal torus bundles with constant Hflux. Employing conformal field theory techniques, the non-commutative and nonassociative structures among generalized coordinates in the so call...
متن کاملT-duality, quotients and generalized Kähler geometry
In this paper we reopen the discussion of gauging the two-dimensional off-shell (2, 2) supersymmetric sigma models written in terms of semichiral superfields. The associated target space geometry of this particular sigma model is generalized Kähler (or bi-hermitean with two noncommuting complex structures). The gauging of the isometries of the sigma model is now done by coupling the semichiral ...
متن کاملT-duality and Generalized Complex Geometry
We find the explicit T-duality transformation in the phase space formulation of the N = (1, 1) sigma model. We also show that the T-duality transformation is a symplectomorphism and it is an element of O(d, d). Further, we find the explicit T-duality transformation of a generalized complex structure. We also show that the extended supersymmetry of the sigma model is preserved under the T-duality.
