论文摘要
我们解决了以独立方式确定通货膨胀特征的问题。我们从最近提出的方程式开始，该方程式可以准确地计算出地平线上$ ϕ_k $的通电量的值。然后，我们使用此方程的等效形式编写一个公式，该公式将Horizon Crossing的电子折数与枢轴尺度$ N_ {KE}+N_ {EP} $与Tensor到Scalar to-Scalar index $ r $相关联，因此，$ n_ {ke}+n_}+n_}+n_ {ep} $ collists of tos。 $ n_ {ke} $是通货膨胀期间比例因子$ a_k $的电子折数，到通货膨胀结束到$ a_e $ $ a_e $，$ n_ {ep} $是从$ a_e $到枢轴级尺度$ a_p $的电子折数量。特别是，目前，$ r <0.063 $含义$ n_ {ke}+n_ {ep} <112.5 $ e-e folds $ k = k_p $和128.1 e-folds the calace in avaiumber模式$ k_0 $。在通货膨胀时期，我们还对宇宙的大小进行了下限，这引起了当前可观察到的宇宙。我们还讨论了通货膨胀模型退化的问题，并认为只能通过研究重新加热时期的模型预测来解决这种退化。
We address the problem of determining inflationary characteristics in a model independent way. We start from a recently proposed equation which allows to accurately calculate the value of the inflaton at horizon crossing $ϕ_k$. We then use an equivalent form of this equation to write a formula that relates the number of e-folds from horizon crossing to the pivot scale $N_{ke}+N_{ep}$ with the tensor-to-scalar index $r$, hence a general bound for $N_{ke}+N_{ep}$ follows. $N_{ke}$ is the number of e-folds from the scale factor $a_k$ during inflation to the end of inflation at $a_e$ and $N_{ep}$ is the number of e-folds from $a_e$ to the pivot scale factor $a_p$. In particular, at present $r < 0.063$ implies $N_{ke}+N_{ep}< 112.5$ e-folds at $k=k_p$ and 128.1 e-folds at the present scale with wavenumber mode $k_0$. We also give a lower bound to the size of the universe during the inflationary epoch that gave rise to the current observable universe. We also discussed the problem of degeneracy of inflationary models and argue that this degeneration can only be resolved by studying model predictions from the reheating epoch.
