论文摘要
我们考虑了在没有物质的情况下,FLRW指标在Cubic F(R)重力框架中描述的均质和各向同性空间的动力学的可能方法。本文指出了一种限制扩展重力模型参数的方法。在最简单的示例中,我们基于指标的指标动力学提出并开发了F(R)重力模型的方法。讨论了参数和初始条件对进一步动态的影响。参数可以受到1)空间缓慢的限制,2)不稳定性,3)与通货膨胀情况下的分歧。
We consider a possible ways of the dynamics of a homogeneous and isotropic space described by the FLRW metric in the framework of cubic f(R) gravity in the absence of matter. This article points an method for limiting the parameters of extended gravity models. We propose and develop a method for f(R) gravity models based on the dynamics of metrics for various model parameters in the simplest example. The influence of parameters and initial conditions on further dynamics are discussed. The parameters can be limited by 1) slow growth of space, 2) instability, 3) divergence with the inflationary scenario.
