Resumo

We show that the holonomy of the supercovariant connection of IIB supergravity is contained in SL(32, ). We also find that the holonomy reduces to a subgroup of SL(32 − N) ⋉ (⊕N 32−N) for IIB supergravity backgrounds with N Killing spinors. We give the necessary and sufficient conditions for a IIB background to admit N Killing spinors. A IIB supersymmetric probe configuration can involve up to 31 linearly independent planar branes and preserves one supersymmetry.
