Relaxation dominated cosmological expansion
arXiv:gr-qc/9601033 · doi:10.1016/0375-9601(96)00024-2
Abstract
The behavior near the singularity of an isotropic, homogeneous cosmological model with a viscous fluid source is investigated. This turns out to be a relaxation dominated regime. Full extended irreversible thermodynamics is used, and comparison with results of the truncated theory is made. New singular behaviors are found and it is shown that a relaxation dominated inflationary epoch may exist for fluids with small heat capacity.
