Iib Supergravity and E 10
We analyse the geodesic E 10 /K(E 10) σ-model in a level decomposition w.r.t. the A 8 × A 1 subalgebra of E 10 , adapted to the bosonic sector of type IIB supergravity, whose SL(2, R) symmetry is identified with the A 1 factor. The bosonic supergravity equations of motion, when restricted to zeroth and first order spatial gradients, are shown to match with the σ-model equations of motion up to ...
متن کاملSuperalgebraic Truncations from D=10, N=2 Chiral Supergravity
We study ten-dimensional N=2 maximal chiral supergravity in the context of Lie superalgebra SU(8/1). The possible successive superalgebraic truncations from ten dimensional N=2 chiral theory to the lower dimensional supergravity theories are systematically realized as sub-superalgebraic chains of SU(8/1) by using the Kac-Dynkin weight techniques.

متن کاملN = 1 No - Scale Supergravity from Iib Orientifolds
We describe the low-energy effective theory of N=1 spontaneously broken supegrav-ity obtained by flux-induced breaking in the presence of n D3 branes. This theory can be obtained by integrating out three massive gravitino multiplets in the hierarchical breaking N = 4 → 3 → 2 → 1 of a N=4 orientifold. This integration also eliminates the IIB complex dilaton. The resulting theory is a no-scale su...
متن کاملGauged Supergravity from Type IIB
We construct the complete and explicit non-linear Kaluza-Klein ansatz for deriving the bosonic sector of N = 4 SU (2) × U (1) gauged five-dimensional supergravity from the reduction of type IIB supergravity on S 5. This provides the first complete example of such an S 5 reduction that includes non-abelian gauge fields, and it allows any bosonic solution of the five-dimensional N = 4 gauged theo...
متن کاملChiral Superfields in IIB Supergravity
The field strength superfield of IIB supergravity on AdS5 × S5 is expanded in harmonics on S5 with coefficients which are D = 5, N = 8 chiral superfields. On the boundary of AdS5 these superfields map to D = 4, N = 4 chiral superfields and both sets of superfields obey additional fourth-order constraints. The constraints on the D = 4, N = 4 chiral fields are solved using harmonic superspace in ...
