Abstract
We consider the cosmological role of the scalar fields generated by the compactification of 11-dimensional Einstein gravity on a 7-dimensional elliptic twisted torus, which has the attractive features of giving rise to a positive semidefinite potential, and partially fixing the moduli. This compactification is therefore relevant for low-energy $M$-theory, 11-dimensional supergravity. We find that there is no slow-roll inflation within a subclass of these twisted tori and give evidence that this result extends to a more general situation. Despite the lack of slow-roll, we find that there is a novel scaling solution in Friedmann cosmologies in which the massive moduli oscillate but maintain a constant energy density relative to the background barotropic fluid.
