Causal Thermodynamics

We study a closed model of a universe filled with viscous fluid and quintessence matter components. The dynamical equations imply that the universe might look like an accelerated flat Friedmann–Robertson–Walker (FRW) universe at low redshift. We consider here dissipative processes which obey a causal thermodynamics. Here, we account for the entropy production via causal dissipative inflation.

Universe Evolution

A new phenomenological decay law for the cosmological Λ-term is proposed and its influence on the universe evolution is investigated. Unlike the standard FRW model are the possibility of nonsingular solutions, recollapsing open universes and an everexpanding closed model. Explicit analytic solutions are given for the flat case both for parametric and cosmological times. In this case, models with the present density parameter Ω0 smaller than 2/3 and age bigger than [Formula: see text] can always be obtained. It is also shown that kinematic expressions as the luminosity distance and angular diameter versus redshift relation are significantly modified.
