论文摘要
在本文中，我们研究了爱因斯坦 - 希尔伯特（Einstein-Hilbert）与曲率标量$ r $的混合组合，以及在通货膨胀场景中的palatini Gravity中的功能$ f（\ Mathcal {r}）$的函数$ f（\ Mathcal {r}）$，从Swampland猜想的角度来看。在最近的宇宙学研究中，该混合模型已引起人们的注意，并且在文献中广泛研究了其应用。在这方面，使用swampland猜想（使用（使用（$ c_ {1} $）作为DS Swampland猜想的第一个组成部分），这是从潜在的第一个衍生物中获得的，并且（$ c_ {2} $）是（$ c_ {2} $）作为第二个组成部分，是从潜在的第二个衍生物中获得的第二个组成部分，我们将范围的第二个元素获得的效果，我们在一个范围的范围中获得了依赖的范围。通货膨胀方案要获得宇宙学数量，例如慢滚参数，标量光谱索引$（n_ {s}）$，张量表与量表比（$ r_ {s} $），然后将它们与宇宙学观测值进行比较。此外，我们通过将Swampland猜想应用于$ r_ {s} -n_ {s} $，$ c_ {1,2} -n_ {s} $ c_ {s} $和$ c_ {1,2} -r_ {1,2} -r_ {s} $ plots。
In this paper, we study a hybrid combination of Einstein-Hilbert action with curvature scalar $R$, and a function $f(\mathcal{R})$ in Palatini gravity within the context of inflationary scenario, from the Swampland conjecture point of view. This hybrid model has been paid attention in recent cosmological studies, and its applications have been widely studied in the literature. In this regard, using the Swampland conjecture (using ($ C_ {1} $) as the first component of dS swampland conjecture, which is obtained from the first derivative of the potential upon the potential and ($ C_ {2} $) as the second component which is acquired from the second derivative of the potential upon the potential), we investigate the cosmological implications of the present gravity theory, with a suitable potential, in the framework of inflationary scenario to obtain cosmological quantities such as slow-roll parameter, scalar spectral index $(n_{s})$, tensor-to-scalar ratio ($r_{s}$), and then compare them with the cosmological observations. Moreover, we compare the compatibility or incompatibility of the model with observable data, such as Planck, by applying Swampland conjecture to $r_{s}-n_{s}$ , $C_{1,2}-n_{s}$ and $C_{1,2}-r_{s}$ plots.
