Qualitative analysis of dissipative cosmologies
arXiv:gr-qc/0010021 · doi:10.1103/PhysRevD.63.023501
Abstract
The evolution of an homogeneous and isotropic dissipative fluid is analyzed using dynamical systems techniques. The dissipation is driven by bulk viscous pressure and the truncated Israel-Stewart theory is used. Although almost all solutions inflate, we show that only few of them can be considered as physical solutions since the dominant energy condition is not satisfied.
