Qualitative viscous cosmology.

چکیده
The Full (non–truncated) Israel–Stewart theory of bulk viscosity is applied to dissipative FRW spacetimes. Dimensionless variables and dimensionless equations of state are used to write the Einstein–thermodynamic equations as a plane autonomous system and the qualitative behaviour of this system is determined. Entropy production in these models is also discussed. 04.20.Jb, 98.80.Hw Typeset using REVTEX ∗Current Address: Department of Mathematics and Computer Science, St. Francis Xavier University, Antigonish, Nova Scotia, B2G 2W5 †Member of Center for Nonlinear Studies, Witwatersand University, South Africa 2050 1

Nonstandard Cosmology With Constant and Variable Gravitational and Variable Cosmological “Constants” and Bulk Viscosity
We have analyzed a nonsingular model with a variable cosmological term following the Carvalho et al. ansatz. The model was shown to approximate to the model of Freese et al. in one direction and to the Özer-Taha in the other. We have then included the effect of viscosity in this cosmology, as this effect has not been considered before. The analysis showed that this viscous effect could be impor...
متن کاملDark energy and viscous cosmology
Singularities in the dark energy universe are discussed, assuming that there is a bulk viscosity in the cosmic fluid. In particular, it is shown how the physically natural assumption of letting the bulk viscosity be proportional to the scalar expansion in a spatially flat FRW universe can drive the fluid into the phantom region (w < −1), even if lies in the quintessence region (w > −1) in the n...
متن کاملViscous Generalized Chaplygin Gas
Viscous GCG(generalized Chaplygin gas) cosmology is discussed, assuming that there is bulk viscosity in the linear barotropic fluid and GCG. The dynamical analysis indicates that the phase wg = −1 + √ 3γκτg/(γ − √ 3κτγ) is a dynamical attractor and the equation of state of GCG approaches it from either wg > −1 or wg < −1 depending on the choice of its initial cosmic density parameter and the ra...
متن کاملViscous Cosmology Andthe Cardy-verlinde For- Mula
The holographic principle in a radiation dominated universe is extended to incorporate the case of a bulk-viscous cosmic fluid. This corresponds to a nonconformally invariant theory. Generalization of the Cardy-Verlinde entropy formula to the viscous case appears to be possible from a formal point of view, although we question on physical grounds the manner in which the Casimir energy is evalua...
متن کاملWormholes in Bulk Viscous Cosmology
We investigate the effects of the accretion of phantom energy with non-zero bulk viscosity onto a Morris-Thorne wormhole. We have found that if the bulk viscosity is large then the mass of wormhole increases rapidly as compared to small or zero bulk viscosity.
