Abstract
In the present work we perform a phase-plane analysis of the complete dynam ical system corresponding to a flat FRW cosmological models with a perfect fluid and a self-interacting scalar field and show that every positive and monotonous potential which is asymptotically exponential yields a scaling s olution as a global attractor, (C) 2000 Published by Elsevier Science B.V.
