Abstract

We report on the formulation of $N = 2$ $D = 4$ supergravity coupled to $n_{V}$ abelian vector multiplets in presence of electric and magnetic charges. General formulae for the (moduli dependent) electric and magnetic charges for the $n_{V} + 1$ gauge fields are given which reflect the symplectic structure of the underlying special geometry. The specification to Type IIB strings compactified on Calabi-Yau manifolds, with gauge group $U (1)^{h_{21} + 1}$ is given.
