The methods of supergravity allow us to derive a multi-field F-term potential. Using this, we denote a generic and non-positive single-field F-term potential. We insert our theory into the scalar-gravity part of the (2,1|1) invariant superconformal action. That action leads us to a de Sitter solution at the inflationary trajectory. One can denote stabilization of fields in terms of the Khler kinetic terms and single-field slow-roll inflation parameters. We combine these with the de Sitter swampland conjecture to generate a bounded conjecture. This approach allowed us to show that the single field slow-roll inflation works in harmony with bounded de Sitter conjecture for any concave inflation potential.

通过超重力解决德西特沼泽猜想与暴胀张力

超重力方法使我们能够推导出多场 F 项势。使用它,我们表示一个通用的和非正的单场 F 项潜力。我们将我们的理论插入到 (2,1|1) 不变超共形作用的标量重力部分。这一行动将我们引向了通货膨胀轨迹上的德西特解决方案。可以用 Khler 动力学项和单场慢滚膨胀参数来表示场的稳定。我们将这些与 de Sitter swampland 猜想相结合以产生有界猜想。这种方法使我们能够证明单场慢滚暴胀与任何凹暴胀势的有界德西特猜想相一致。
