Abstract

We present a phase-space analysis of cosmology containing multiple scalar fields with positive and negative exponential potentials. In addition to the well-known assisted inflationary solutions, there exits power-law multi-kinetic-potential scaling solutions for sufficiently flat positive potentials or steep negative potentials, which are the unique late-time attractor whenever they exist. We briefly discuss the physical consequences of these results.
