TL;DR: In this article, a super-critical (Liouville) string cosmology is discussed in the context of a target-space two-dimensional string cosmological model, and a numerical analysis indicates that the identification of time with the Liouville mode results in an expanding universe with matter which exhibits an inflationary phase, and graceful exit from it, tending asymptotically to a flat-metric fixed point.
