Bouncing Cosmologies
摘要：
我们回顾了非奇异宇宙（{ \em，即}）的一般特征.那些从加速坍缩的时代到膨胀的时代而不显示奇点的宇宙）以及循环宇宙。我们讨论反弹背后的机制，并分析实现这些机制的解决方案的例子。观测结果，这种经常宇宙学也被认为是，重点是在行为的扰动。
英文摘要：
We review the general features of nonsingular universes ({\em i.e.} those that go from an era of accelerated collapse to an expanding era without displaying a singularity) as well as cyclic universes. We discuss the mechanisms behind the bounce, and analyze examples of solutions that implement these mechanisms. Observational consequences of such regular cosmologies are also considered, with emphasis in the behavior of the perturbations.
