Resumen:
We analyze D = 4 compactifications of Type IIB theory with generic, geometric
and non-geometric, dual fluxes turned on. In particular, we study N = 1
toroidal orbifold compactifications that admit an embedding of the untwisted
sector into gauged N = 4, 8 supergravities. Truncations, spontaneous breaking
of supersymmetry and the inclusion of sources are discussed. The algebraic
identities satisfied by the supergravity gaugings are used to implement the
full set of consistency constraints on the background fluxes. This allows to
perform a generic study of N = 1 vacua and identify large regions of the
parameter space that do not admit complete moduli stabilization. Illustrative
examples of AdS and Minkowski vacua are presented.
