论文摘要
考虑到ϕ和背景度量之间的最小耦合，宇宙的时空已在标量场$ ϕ $下受到干扰。爱因斯坦场方程的溶液已在扰动的几何形状下获得，相应的保护方程式显示了宇宙流体的非平衡热力学处方。遵循宇宙流体的稳定性标准以及热力学定律，对$ ϕ $的选择施加了一些限制。
The space-time of the Universe has been perturbed under a scalar field $ϕ$ considering the minimum coupling between ϕ and the background metric. The solutions of Einstein field equations have been obtained under perturbed geometry and the corresponding conservation equation shows the non-equilibrium thermodynamic prescription of the cosmic fluid. Following the stability criteria of the cosmic fluid along with the laws of thermodynamics, some constraints have been imposed on the choice of $ϕ$.
