论文摘要
在本文中，我们研究了晚期宇宙的模型，该模型与同质，各向同性和平坦的Friedmann-Robertson-Walker指标，其中重力场的来源基于Fermion和Boson Field，其中Maxwell Term $ f_ {μ{μNV} f^{μndimensionsin 4 Dimensions中。麦克斯韦对爱因斯坦重力的驱动使得可以找到新的方法来解决观察到的宇宙加速扩张的问题。已经获得并研究了能量条件。这些条件对能量密度和压力的行为施加了非常简单和独立的限制，因为它们不需要特定的物质方程。要考虑模型，实现了能源条件NEC，WEC，DEC，并违反了SEC条件。玻色子和费米恩场在早期的加速度负责，但是由于总压力趋向于零，因此发生了向减速状态的过渡。麦克斯韦球场仅在早期至关重要。
In this paper, we study the model of the late universe with the homogeneous, isotropic and flat Friedmann-Robertson-Walker metric, where the source of the gravitational field is based on the fermion and boson field, with the Maxwell term $F_{μν}F^{μν} $ in four dimensions. The actuation of the Maxwell term for the Einstein gravity makes it possible to find new approaches to solve the problem of the observed accelerated expansion of the universe. Energy conditions have been obtained and studied. These conditions impose very simple and model-independent restrictions on the behaviour of energy density and pressure since they do not require a specific equation of state of matter. To consider the model, the energy conditions NEC, WEC, DEC are realized, and the SEC condition is violated. The boson and fermion fields are responsible for the accelerated regime at early times, but since the total pressure is tending toward zero for large times, a transition to a decelerated regime occurs. Maxwell field is crucial only in the early times.
