IIB solutions with N > 28 Killing spinors are maximally supersymmetric
We show that all IIB supergravity backgrounds which admit more than 28 Killing spinors are maximally supersymmetric. In particular, we find that for all N > 28 backgrounds the supercovariant curvature vanishes, and that the quotients of maximally supersymmetric backgrounds either preserve all 32 or N < 29 supersymmetries.
متن کاملGeometries with Killing Spinors and Supersymmetric AdS Solutions
The seven and nine dimensional geometries associated with certain classes of supersymmetric AdS3 and AdS2 solutions of type IIB and D = 11 supergravity, respectively, have many similarities with Sasaki-Einstein geometry. We further elucidate their properties and also generalise them to higher odd dimensions by introducing a new class of complex geometries in 2n+2 dimensions, specified by a Riem...
متن کاملType IIB Killing spinors and calibrations
In this paper we derive the full set of differential equations and some algebraic relations for p-forms constructed from type IIB Killing spinors. These equations are valid for the most general type IIB supersymmetric backgrounds which have a non-zero NS-NS 3-form field strength, H , and non-zero R-R field strengths, G, G and G. Our motivation is to use these equations to obtain generalised cal...
متن کاملMaximally supersymmetric G-backgrounds of IIB supergravity
We classify the geometry of all supersymmetric IIB backgrounds which admit the maximal number of G-invariant Killing spinors. For compact stability subgroups G = G2, SU(3) and SU(2), the spacetime is locally isometric to a product Xn × Y10−n with n = 3, 4, 6, where Xn is a maximally supersymmetric solution of a n-dimensional supergravity theory and Y10−n is a Riemannian manifold with holonomy G...
متن کاملThe Classification of Highly Supersymmetric Supergravity Solutions
The spinorial geometry method is an effective method for constructing systematic classifications of supersymmetric supergravity solutions. Recent work on analysing highly supersymmetric solutions in type IIB supergravity using this method is reviewed [1, 2]. It is shown that all supersymmetric solutions of IIB supergravity with more than 28 Killing spinors are locally maximally supersymmetric.
