✦ Synopsis
We criticize and generalize some properties of No ther charges presented in a paper by V. Iyer and R. M. Wald and their application to entropy of black holes. The first law of black holes thermodynamics is proven for any gauge natural field theory. As an application charged Kerr Newman solutions are considered. As a further example we consider the (1+2) BTZ black hole solution.

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
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
