BPS black holes, supersymmetry and orbits of exceptional groups

Abstract

We report on duality invariant constraints, which allow a classification of BPS black holes preserving different fractions of supersymmetry. We then relate this analysis to the orbits of the exceptional groups $E_{6(6)},E_{7(7)}$, relevant for black holes in five and four dimensions.
