A Brief Review of the Singularities in 4D and 5D Viscous Cosmologies Near the Future Singularity
I. Brevik, O. Gorbunova
Analytic properties of physical quantities in the cosmic fluid such as energy density ρ(t) and Hubble parameter H(t) are investigated near the future singularity (Big Rip). Both 4D…
Viscous Dark Cosmology with Account of Quantum Effects
I. Brevik, O. Gorbunova
The analytic properties of the energy density rho(t) of the cosmic fluid, and the Hubble parameter H(t), are investigated near to the future singularity t=t_s assuming different fo…
A FRW Dark Fluid with a Non-Linear Inhomogeneous Equation of State
I. Brevik, E. Elizalde, O. Gorbunova +1
A dark Friedman-Robertson-Walker fluid governed by a non-linear inhomogeneous equation of state is considered which can be viewed as a conveniently simple paradigm for a whole clas…
Dark Energy Fluid with Time-Dependent, Inhomogeneous Equation of State
I. Brevik, O. G. Gorbunova, A. V. Timoshkin
The four-dimensional Friedman flat universe, filled with an ideal fluid with a linear (oscillating) inhomogeneous equation of state (EoS) depending on time, is studied. The equatio…
