摘要：

Several isotropic, homogeneous cosmological models containing a self-interacting minimally coupled scalar field, a perfect fluid source and cosmological constant are solved, New exact, asymptotically stable solutions with an inflationary regime or a final Friedmann stage are found for some simple, interesting. potentials. It is shown that the fluid and the curvature may determine how these models evolve for large times.
