| dc.description.abstract | We explore flat ACDM models with bulk viscosity,
and study the role of the bulk viscosity in the evolution
of these universe models. The dynamical equations for these
models are obtained and solved for some cases of bulk viscosity.
We obtain differential equations for the Hubble parameter
H and the energy density of dark matter ρm, for
which we give analytical solutions for some cases and for
the general case we give a numerical solution. Also we calculate
the statefinder parameters for these models and display
them in the s–r-plane. | en_US |
