| Abstract: | Dynamical behaviors and stability properties of a flat space Friedmann-Robertson-Walker universe filled with pressureless dark matter and viscous dark energy are studied in the context of standard classical and loop quantum cosmology.Assuming that the dark energy has a constant bulk viscosity,it is found that the bulk viscosity effects influence only the quintessence model case leading to the existence of a viscous late time attractor solution of deSitter type,whereas the quantum geometry effects influence the phantom model case where the big rip singularity is removed.Moreover,our results of the Hubble parameter as a function of the redshift are in good agreement with the more recent data. |
