具有f -本质的FRW宇宙学的Noether对称性
Noether symmetry of FRW cosmology with f - essence
摘要:
本文研究了f-本质背景下与引力非最小耦合时的宇宙动力学。利用Noether定理得到了f-本质的耦合函数和Lagrange函数的显式表达式。因此,对于这个模型,描述宇宙加速膨胀的宇宙学参数是确定的。
英文摘要:
In this paper, we investigate the dynamics of the universe on the background of f-essence when a non-minimal coupling with gravity. Field equations are obtained and using the Noether theorem, explicit forms of the coupling function and the Lagrange function of the f-essence were obtained. Accordingly, for this model, the cosmological parameters that describe the accelerated expansion of the universe are determined.
