Super-Ehlers in any dimension


We classify the enhanced helicity symmetry of the Ehlers group to extended supergravity theories in any dimension. The vanishing character of the pseudo-Riemannian cosets occurring in this analysis is explained in terms of Poincaré duality .The latter resides in the nature of regularly embedded quotient subgroups which are noncompact rank preserving.
