摘要:

我们提出了一个自治相平面,描述了包含年龄暗能量的场方程在5D Brans-Dicke宇宙学中的演化。为了观测验证数值结果,我们同时解决方程约束的模型参数与超新星Ia数据。我们发现临界点(宇宙状态)的存在和稳定性的条件,并数值研究宇宙学参数。我们还研究了该模型的状态发现者诊断。

英文摘要:

We present an autonomous phase-plane describing the evolution of field equations containing an agegraphic dark energy in 5D Brans- Dicke cosmology. To observationally verify the numerical results, we simultaneously solve the equations by constraining the model parameters with SNe Ia data. We find conditions for the existence and stability of the critical points (states of the universe) and numerically examine the cosmological parameters. We also investigate the model by means of statefinder diagnostic.
