Solutions to CDM Universe Derived from Global Brane Model
Yongli Ping, Lixin Xu, Baorong Chang +2
An exact solution of brane universe is studied and the result indicates that Friedmann equations on the brane are modified with an extra term. This term can play the role of dark e…
Power-law cosmological solution derived from DGP brane with a brane tachyon field
Yongli Ping, Lixin Xu, Hongya Liu +1
By studying a tachyon field on the DGP brane model, in order to embed the 4D standard Friedmann equation with a brane tachyon field in 5D bulk, the metric of the 5D spacetime is pr…
Using Energy Conditions to Distinguish Brane Models and Study Brane Matter
Yongli Ping, Lixin Xu, Baorong Chang +1
Current universe (assumed here to be normal matter on the brane) is pressureless from observations. In this case the energy condition is and . By using this condi…
Correspondence Between DGP Brane Cosmology and 5D Ricci-flat Cosmology
Yongli Ping, Lixin Xu, Hongya Liu
We discuss the correspondence between the DGP brane cosmology and 5D Ricci-flat cosmology by letting their metrics equal each other. By this correspondence, a specific geometrical…
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…
The Real Scalar Field Equation for Nariai Black Hole in the 5D Schwarzschild-de Sitter Black String Space
Molin Liu, Hongya Liu, Chunxiao Wang +1
The Nariai black hole, whose two horizons are lying close to each other, is an extreme and important case in the research of black hole. In this paper we study the evolution of a m…
