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 mas s formula.
