Abstract

We illustrate the correspondence between the N =1 superstring compactifications with fluxes, the N = 4 gauged supergravities and the superpotential and Kähler potential of the effective N = 1 supergravity in four dimensions. In particular we derive, in the presence of general fluxes, the effective N = 1 supergravity theory associated to the type IIA orientifolds with D6 branes, compactified on T^6^/(Z~2~× Z~2~). We construct explicit examples with different features: in particular, new IIA no‐scale models, new models with cosmological interest and a model which admits a supersymmetric AdS~4~ vacuum with all seven main moduli (S, T~A~, U__~A~__,A = 1,2,3) stabilized.
