最近有人猜测弦理论不承认德西特临界点。本文指出，在几种情况下，包括KKLT或赛道模型，这种说法相当于不存在超对称Minkowski或AdS解。这种等价性来自于在大半径极限中建立电势的正性，在达到AdS真空之前需要电势的翻转。例如，这个猜想与最简单的1-模KKLT AdS超对称解是不相容的。
It has recently been conjectured that string theory does not admit de Sitter critical points. This note points out that in several cases, including KKLT or racetrack models, this statement is equivalent to the absence of supersymmetric Minkowski or AdS solutions. This equivalence arises from establishing the positivity of the potential in a large-radius limit, requiring a turnover of the potential before reaching an AdS vacuum. For example, this conjecture is incompatible with the simplest 1-modulus KKLT AdS super symmetric solution.
