Abstract
We investigate cosmological models with a free scalar field and a visc ous fluid. We find exact solutions for a linear and nonlinear viscosit y pressure. Both yield singular and bouncing solutions. In the first r egime, a de Sitter stage is asymptotically stable, while in the second case we find power-law evolutions for a vanishing cosmological consta nt.
