摘要:

近年来,研究人员一直在研究各种条件作为宇宙学意义上的沼泽地标准。他们研究了许多不同沼泽条件下的通货膨胀模型。有时,这些猜测会被修改并得出令人着迷的观点。沼泽地猜想与慢卷单场暴胀模型相矛盾。因此,本文将简要地描述用特殊方法解决这个矛盾,我们考虑一个关于暴胀中耦合函数的小参数λ,解决这个重要的对立。在此基础上,我们将从一个新的角度讨论基于沼泽地准则的通货膨胀模型。因此,我们引入了一些通货膨胀模型,并对沼泽地标准提出了挑战。我们根据最新的观测数据,将宇宙学参数的允许范围定义为张量标量比(r)和标量谱指数(ns)。接下来,我们研究了新的约束条件,以确定相应的模型与沼泽地地形的兼容性或不兼容性。最后,我们将结果表达出来,并通过绘制一些图形将它们与最新的观测数据进行比较。

英文摘要:

Recently researchers have been studying various conditions as swampland criteria in cosmological implications. They have studied many inflation models with different swampland conditions. Occasionally these conjectures are modified and lead to fascinating points. The swampland conjecture is in contradiction with the slow-roll single-field inflation model. So in this paper, we will briefly describe resolving this contradiction with the special method; we consider a small parameter λ with respect to a coupling function in inflation and resolve this important antithesis. Then we will discuss a new point of view in studying inflation models according to the swampland criteria. Therefore we introduce some inflation models and challenge the swampland criteria. We specify the allowable range of cosmological parameters as the tensor-to-scalar ratio (r) the scalar spectral index (ns) according to the latest observable data. Next, we study the new constraints to determine the compatibility or incompatibility of the corresponding model with the swampland conjectures. Finally, we express the results and compare them with the latest observational data by plotting some figures.
