Viscous generalized Chaplygin gas
Xiang-hua Zhai, You-dong Xu, Xin-zhou Li
Viscous GCG(generalized Chaplygin gas) cosmology is discussed, assuming that there is bulk viscosity in the barotropic fluid and GCG. The dynamical analysis indicates that the phas…

On the Quintessence with Abelian and Non-abelian Symmetry
Xin-zhou Li, Jian-gang Hao, Dao-jun Liu +1
We study the perturbations on both "radial" and "angular" components of the quintessence with an internal abelian and non-abelian symmetry. The properties of the perturbation on th…
