论文摘要
我们在标量场中重新审视循环宇宙场景FRW宇宙学，并检查其适用于非微耦合标量场的适用性。我们表明，对于最受欢迎的四分之一潜力的情况，并且标准的非微小耦合这种情况确实有效。另一方面，我们确定了循环模型无法正常工作并提出相应原因的某些情况。
We revisit the cyclic Universe scenario in scalar field FRW cosmology and check its applicability for a nonminimally coupled scalar field. We show that for the most popular case of a quartic potential and the standard nonminimal coupling this scenario does work. On the other hand, we identify certain cases where cyclic model fails to work and present corresponding reasons for this.
