摘要：
We report on some general results on the physics of extremal BPS black holes in four and five dimensions. The duality-invariant entropy-formula for all N > 2 extended supergravities is derived. Its relation with the fixed-scalar condition for the black-hole "potential energy" wich extremizes the BPS mass is obtained. BPS black holes preserving different fractions of supersymmetry are classified in a U-duality invariant set up. The latter deals with different orbits of the fundamental representations of the exceptional groups E-7(7) and E-6(6). We comment upon the interpretation of these results in a string and M-theory framework.
