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 ªflat symplectic bundlesº and central charges may be defined as ªsectionsº over these bundle

The derivation of absolute (moduli-independent) U-invariants for all N > 2 extended supergravities at D = 4 in terms of (moduli-dependent) central and matter charges is reported. These invariants give a general denition of the \topological" Bekenstein{Hawking entropy formula for extremal black-holes
