    • Abstract

       

      We report some results on the relation between extremal black holes in locally supersymmetric theories of gravity and groups of type $E_7$, appearing as generalized electric-magnetic duality symmetries in such theories. Some basics on the covariant approach to the stratification of the relevant symplectic representation are reviewed, along with a connection between special Kähler geometry and a ‘generalization’ of groups of type $E_7$.
