Abstract
We discuss the entropy and the transformation properties of classical extremal N=2 black hole solutions in supergravity theories associated with the minimal coupling models CP (n - 1,1). The entropy is given by a manifestly invariant quantity under the embedding of the duality group SU (1,n) into Sp (2n + 2) which is a symmetry of the classical BPS mass formula.Keywords
