论文摘要
我们研究了特定$ f（r）$模型的宇宙通货膨胀方案，该场景包含$ r $的一个以上的高阶期限。此处考虑的$ f（r）$具有$ r^2 $，$ r^3 $和$ r^4 $以及线性术语。在存在这些高阶术语的情况下，已经进行了严格的研究，以找出它是否导致身体上明智的宇宙通货膨胀模型。我们详细研究了这种条件的$ f（r）$模型使通货膨胀方案变得可行，并且发现我们研究的结果与最近的普朗克结果非常吻合。
We investigate the cosmic inflation scenario of a specific $f(R)$ model that contains more than one higher-order term in $R$. The $f(R)$ considered here has the terms $R^2$, $R^3$, and $R^4$ along with the linear term. A rigorous investigation has been carried out in the presence of these higher-order terms to figure out whether it leads to a physically sensible cosmic inflationary model. We examine in detail, subject to which conditions this $f(R)$ model renders a viable inflationary scenario, and it has been found that the outcomes of our study agree well with the recent PLANCK results.
