T-duality in Ramond-Ramond backgrounds

Target space duality is a symmetry of string theory that maps a string theory in a background to a dual string theory in a dual background. For reviews see [1][2]. The map between T-dual backgrounds was derived in a world-sheet path integral formalism for Neveu-Schwarz NeveuSchwarz fields in [3]. For Ramond-Ramond backgrounds in type II, various derivations have appeared in the literature: the ...

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...

On Fermionic T-duality of Sigma modes on AdS backgrounds

We study the fermionic T-duality symmetry of integrable Green-Schwarz sigma models on AdS backgrounds. We show that the sigma model on AdS5 × S1 background is self-dual under fermionic T-duality. We also construct new integrable sigma models on AdS2 ×CPn. These backgrounds could be realized as supercosets of SU supergroups for arbitrary n, but could also be realized as supercosets of OSp superg...

Generalized Duality in Curved String-Backgrounds

The elements of O(d, d,Z) are shown to be discrete symmetries of the space of curved string backgrounds that are independent of d coordinates. The explicit action of the symmetries on the backgrounds is described. Particular attention is paid to the dilaton transformation. Such symmetries identify different cosmological solutions and other (possibly) singular backgrounds; for example, it is sho...

On type II superstrings in bosonic backgrounds: the role of fermions and T-duality

We derive the actions for type II Green-Schwarz strings up to second order in the fermions, for general bosonic backgrounds. We base our work on the so-called normal coordinate expansion. The resulting actions are κ-symmetric and, for the case of surviving background supersymmetries, supersymmetric. We first obtain the type IIa superstring action from the 11D supermembrane by double dimensional...
