论文摘要
在这项研究中，将检查具有完美流体和重力框架F（Q）的宇宙学模型。在这种修饰的重力理论中，重力具有F（Q）形式，其中Q代表非金属标量。我创建了两个弹跳的宇宙学模型，其中一种假定Lagrangian F（Q）对Q具有线性依赖性，另一个具有多项式功能形式。已经发现，各个模型的参数在很大程度上决定了它们的行为方式。结果模型的状态方程（EOS）参数捕获了宇宙的讽刺行为。应该强调的是，内置的宇宙学模型违反了能源需求。讨论了模型的运动学和物理特征。
In this study, cosmological models with perfect fluid and a gravitational framework f(Q) will be examined. In this modified theory of gravity, the gravitational force has the form f(Q), where Q stands for the non-metricity scalar. I create two bouncing cosmological models, one in which the Lagrangian f(Q) is assumed to have a linear dependence on Q and the other in which it has a polynomial functional form. It has been discovered that the parameters of the individual models largely determine how they will behave. The resulting models' equation of state (EoS) parameter captures the universe's ironic behavior. It should be highlighted that the built-in cosmological models go against the energy requirements. The models' kinematical and physical characteristics are discussed.
