摘要
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 "flat symplectic bundles" and central charges may be defined as "sections" over these bundles. Attractor points giving rise to "fixed scalars" of the horizon geometry and Beltenstein-Hawking entropy formula for extremal black-holes are discussed in some details.
