我们研究反德西特空间的沼泽地的背景下。特别是，我们推测纯AdS的近平坦极限属于沼泽地，因为它必然伴随着一个无限的光态塔。塔的质量是宇宙常数的幂律，在超对称情况下为1 2的幂。我们讨论了这种行为和其他沼泽地aesthetures之间的关系，如审查的无限数量的无质量领域，和精制德西特猜想。此外，我们建议的AdS半径的变化有一个广义的距离猜想，其中关联的距离变化的所有字段的解释。在这个框架下，我们认为距离Λ→ 0极限的AdS是无限的，导致光塔的状态。我们还讨论了该猜想对德西特空间的影响。
We study aspects of anti-de Sitter space in the context of the Swampland. In particular, we conjecture that the near-flat limit of pure AdS belongs to the Swampland, as it is necessarily accompanied by an infinite tower of light states. The mass of the tower is power-law in the cosmological constant, with a power of 1 2 for the supersymmetric case. We discuss relations between this behaviour and other Swampland conjectures such as the censorship of an unbounded number of massless fields, and the refined de Sitter conjecture. Moreover, we propose that changes to the AdS radius have an interpretation in terms of a generalised distance conjecture which associates a distance to variations of all fields. In this framework, we argue that the distance to the Λ→ 0 limit of AdS is infinite, leading to the light tower of states. We also discuss implications of the conjecture for de Sitter space.
