## Abstract Extremal black holes in extended supergravity theories can be obtained as solutions of first order flow equations even when they are not supersymmetric, provided one identifies a suitable superpotential W appearing in the effective potential, and driving the evolution of the scalar fiel

## Abstract Extremal black holes in MaxwellβEinstein supergravities with scalar fields can be obtained as solutions of first order flow equations even when they are not supersymmetric, provided one identifies a suitable superpotential W entering the effective potential, and driving the evolution of
In these lectures we give a geometrical formulation of N-extended supergravities which generalizes N 2 special geometry of N 2 theories. In all these theories duality symmetries are related to the notion of Βͺflat symplectic bundlesΒΊ and central charges may be defined as ΒͺsectionsΒΊ over these bundle
