摘要

在这项工作中，我们结合广义查普利金启发的通胀模型讨论了德西特沼泽地猜想。我们证明了这些猜想是可以满足的，但仅限于远离广义相对论极限的参数空间区域。宇宙微波背景数据已经限制了该模型允许的暴胀势。我们的结果进一步限制了可能的势。

The de Sitter Swampland Conjectures in the Context of Chaplygin-Inspired Inflation

In this work, we discuss the de Sitter swampland conjectures in the context of the generalized Chaplygin-inspired inflationary model. We demonstrate that these conjectures can be satisfied, but only in the region of the parameter space far away from the General Relativity limit. The cosmic microwave background data had already been found to restrict the allowed inflationary potentials of this model. Our results impose a further limitation on the possible potentials.
