Statefinder diagnostic in a torsion cosmology
Xin-zhou Li, Chang-bo Sun, Ping Xi
We apply the statefinder diagnostic to the torsion cosmology, in which an accounting for the accelerated universe is considered in term of a Riemann-Cartan geometry: dynamic scalar…

Torsion cosmological dynamics
Xin-zhou Li, Chang-bo Sun, Ping Xi
In this paper, the dynamical attractor and heteroclinic orbit have been employed to make the late-time behaviors of the model insensitive to the initial condition and thus alleviat…

Viscous Cardassian universe
Chang-Bo Sun, Jia-Ling Wang, Xin-Zhou Li
The viscous Cardassian cosmology is discussed, assuming that there is a bulk viscosity in the cosmic fluid. The dynamical analysis indicates that there exists a singular curve in t…
