Several parametrization dark energy models comparison with Statefinder hierarchy

Jing-Zhao Qi, Wen-Biao Liu

We employ the Statefinder hierarchy and the growth rate of matter perturbations to explore the discrimination of $Λ$ CDM and some parametrization dark energy models including the Ch…

Dynamical evolution of quintessence cosmology in a physical phase space

Jing-Zhao Qi, Ming-Jian Zhang, Wen-Biao Liu

The phase space analysis of cosmological parameters $Ω_{ϕ}$ and $γ_{ϕ}$ is given. Based on this, the well-known quintessence cosmology is studied with an exponential potential $V(ϕ)=V_…
