Abstract

We show that the isometries of the manifold of scalars in N=2 supergravity in d=5 space-time dimensions can be broken by the supergravity interactions. The opposite conclusion holds for the dimensionally reduced d=4 theories, where the isometries of the scalar manifold are always symmetries of the full theory. These spaces, which form a subclass of the \em special Kähler manifolds, are relevant for superstring compactifications.
