Abstract
We consider massive half-maximal supergravity in d+3 dimensions and compactify it on a symmetric three-space. We find that the static configurations of MinkowskidÃS3 obtained by balancing the positive scalar potential for the dilaton and the flux of a three-form through the three-sphere are unstable. The resulting cosmological evolution breaks supersymmetry and leads to an accelerated expansion in d dimensions.
