Abstract: We present a complete and systematic analysis of the Minkowski extrema of theN=1, D=4 Supergravity potential obtained from type II orientifold models thatare T-duality invariant, in the presence of generalised fluxes. Based on ourprevious work on algebras spanned by fluxes, and the so-called no-go theoremson the existence of Minkowski and-or de Sitter vacua, we perform a partlyanalytic, partly numerical analysis of the promising cases previously hinted.We find that the models contain Minkowski extrema with one tachyonic direction.Moreover, those models defined by the Supergravity algebra so3,1^2 alsocontain Minkowski-de Sitter minima that are totally stable. All Minkowskisolutions, stable or not, interpolate between points in parameter space whereone or several of the moduli go to either zero or infinity, the so-calledsingular points. We finally reinterpret our results in the language of type IIAflux models, in order to show explicitly the contribution of the differentsources of potential energy to the extrema found. In particular, the cases oftotally stable Minkowski-de Sitter vacua require of the presence ofnon-geometric fluxes.
