Abstract
In this paper the second Lyapunov method is used to study the stability of the de Sitter phase of cosmic expansion when the source of the gravitational field is a viscous fluid. Different inflationary scenarios related to reheating and decay of mini-black holes into radiation are investigated using an effective fluid described by time-varying thermodynamical quantities.
