The symplectic structure of N=2 supergravity and its central extension
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 und...

| Sumario: | 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. |
