Compensators 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 کاملMembrane tension and manifest IIB S-duality
A manifestly S-dual, and ‘12 dimensional’, IIB superstring action with an Sl(2;R) doublet of ‘Born-Infeld’ fields is presented. The M-theory origin of the 12th dimension is the M-2-brane tension, which can be regarded as the flux of a 3-form worldvolume field strength. The latter is required by the fact that the M-2-brane can have a boundary on an M-5-brane.
متن کاملS-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 کاملType IIB string theory , S - duality , and generalized cohomology ∗
In the presence of background Neveu-Schwarz flux, the description of the Ramond-Ramond fields of type IIB string theory using twisted K-theory is not compatible with S-duality. We argue that other possible variants of twisted K-theory would still not resolve this issue. We propose instead a possible path to a solution using elliptic cohomology. We also discuss Tduality relation of this to a pre...
