S-Duality and Exact Type IIB Superstring Backgrounds
A geometrical approach in the non-symmetric connection framework is employed to examine the issue of higher order α′ corrections to D=10 type IIB superstring backgrounds with a covariantly constant null Killing isometry and non-zero Ramond-Ramond field content. These describe generalized supersymmetric string waves and were obtained recently by us through the S-duality transformations of purely...
متن کاملSuperstring Compactification and Target Space Duality
This review talk focusses on some of the interesting developments in the area of superstring compactification that have occurred in the last couple of years. These include the discovery that “mirror symmetric” pairs of Calabi–Yau spaces, with completely distinct geometries and topologies, correspond to a single (2,2) conformal field theory. Also, the concept of target-space duality, originally ...
متن کاملCompensators and Manifest Type IIB S - Duality
Using the conformal compensator superfields of N=2 D=4 supergravity, the Type IIB S-duality transformations are expressed as a linear rotation which mixes the compensator and matter superfields. The classical superspace action for D=4 compactifications of Type IIB supergravity is manifestly invariant under this transformation. Furthermore, the introduction of conformal compensators allows a Fra...
متن کاملNew Formulation of the Type IIB Superstring Action in AdS5 × S
Previous studies of the type IIB superstring in an AdS5 × S background are based on a description of the superspace geometry as the quotient space PSU(2, 2|4)/SO(4, 1)× SO(5). This paper develops an alternative approach in which the Grassmann coordinates provide a nonlinear realization of PSU(2, 2|4) based on the quotient space PSU(2, 2|4)/SU(2, 2) × SU(4), and the bosonic coordinates are descr...
