论文摘要
根据最受欢迎的情况，早期的宇宙应该经历一个加速的扩张阶段，称为宇宙通货膨胀，之后将发生标准的大爆炸宇宙学，从而导致辐射主导的时代。但是，通货膨胀情景的细节尚待完全理解。因此，在本文中，我们研究了其他（异国情调的）宇宙学阶段，可能会延迟标准的大爆炸历史的开始，并改变与通货膨胀宇宙学扰动有关的一些理论预测，例如，例如，张量与标准比率的数量级。
According to the most popular scenario, the early Universe should have experienced an accelerated expansion phase, called Cosmological Inflation, after which the standard Big Bang Cosmology would have taken place giving rise to the radiation-dominated epoch. However, the details of the inflationary scenario are far to be completely understood. Thus, in this paper we study if possible additional (exotic) cosmological phases could delay the beginning of the standard Big Bang history and alter some theoretical predictions related to the inflationary cosmological perturbations, like, for instance, the order of magnitude of the tensor-to-scalar ratio $r$.
