Dark Energy in Global Brane Universe
Yongli Ping, Lixin Xu, Chengwu Zhang +1
We discuss the exact solutions of brane universes and the results indicate the Friedmann equations on the branes are modified with a new density term. Then, we assume the new term…
Reconstruction of 5D Cosmological Model From Recent Observations
Chengwu Zhang, Lixin Xu, Yongli Ping +1
We use a parameterized equation of state (EOS) of dark energy to a 5D Ricci-flat cosmological solution and suppose the universe contains two major components: dark matter and dark…
Statefinder Diagnostic for Phantom Model with
Baorong Chang, Hongya Liu, Lixin Xu +1
We investigate the phantom field with potential and dark matter in the spatially flat FRW model. It has been shown by numerical calculation that there is a…
Statefinder Parameters for Five-Dimensional Cosmology
Baorong Chang, Hongya Liu, Lixin Xu +1
We study the statefinder parameter in the five-dimensional big bounce model, and apply it to differentiate the attractor solutions of quintessence and phantom field. It is found th…
Comparison of Supernovae datasets Constraints on Dark Energy
Chengwu Zhang, Lixin Xu, Baorong Chang +1
Cosmological measurements suggest that our universe contains a dark energy component. In order to study the dark energy evolution, we constrain a parameterized dark energy equation…
Statefinder Parameters for Interacting Phantom Energy with Dark Matter
Baorong Chang, Hongya Liu, Lixin Xu +2
We apply in this paper the statefinder parameters to the interacting phantom energy with dark matter. There are two kinds of scaling solutions in this model. It is found that the e…
