abstract
A geometric formulation which describes extended supergravities in any dimension in presence of electric and magnetic sources is presented. In this framework the underlying duality symmetries of the theories are manifest. Particular emphasis is given to the construction of central and matter charges and to the symplectic structure of all D=4, N-extended theories. The latter may be traced back to the existence, for N>2, of a flat symplectic bundle which is the N>2 generalization of N=2 Special Geometry.

Scherk-Schwarz breaking yields a Dirac gravitino whose mixing lacks a local N=1 superspace realization in minimal supergravity and whose matter couplings produce standard scalar thresholds plus UV-dependent Dirac fermion masses.
In pure N=4 Poincaré supergravity, all extremal spherically symmetric attractors (constant or non-constant moduli) preserve 1/4 supersymmetry for generic charges with I4>0; non-BPS attractors cannot occur.
G_S-invariant subsectors yield consistent truncations for pure supergravities and prove that type IIB uplifts of multicharge spindle solutions are always non-regular with eight codimension-six orbifold singularities.

Consistent Truncations from Duality Symmetries and Desingularization of Orbifold Uplifts
G_S-invariant subsectors yield consistent truncations for pure supergravities and prove that type IIB uplifts of multicharge spindle solutions are always non-regular with eight codimension-six orbifold singularities.
