五维宇宙学的状态发现者参数

Statefinder Parameters for Five-Dimensional Cosmology

Baorong Chang, Hongya Liu, Lixin Xu, Chengwu Zhang

摘要:

研究了五维大反弹模型中的状态发现参数,并将其应用于区分quintessence和phantom场的吸引子解。结果表明,这两种吸引子解在参数平面上的演化轨迹有很大的不同,也不同于其它暗能量模型的解的演化轨迹.

英文摘要:

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 that the evolving trajectories of these two attractor solutions in the statefinder parameters plane are quite different, and that are different from the statefinder trajectories of other dark energy models.
