Stability of inflationary solutions driven by a changing dissipative fluid
Luis P. Chimento, Alejandro S. Jakubi, Diego Pavon
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 with reheating and decay of mini-blackholes into radiation are investigated using an effective fluid described by time--varying thermodynamical quantities.
