论文摘要
第一个和第二个弹置猜想（FSC＆SSC）在非批评弦宇宙学中进行了实质性修改，其中宇宙时间与超临界字符串的时间般的liouville模式一起识别。在这种情况下，由于字符串的非关键性，Friedmann方程将获得其他贡献。当人们试图将BOUSSO应用于dilaton采用跨planckian值的状态的熵（如De Sitter阶段）并恢复与FSC的一致性，至少在某些情况下，这些状态可能会变成光线。标量电势的弱重力猜想（WGC）在本工作中讨论的超临界字符串方案中饱和，但前提是，只有一个人使用diLATON如字符串有效动作中显示的DILATON，其动力学术语未符合规范归一化。在非关键的Starobinsky电位的情况下，WGC均被规范差异的DILATON和用于弦乐有效作用中使用的DILATON所满足。
The First and Second Swampland Conjectures (FSC & SSC) are substantially modified in non-critical string cosmology, in which cosmic time is identified with the time-like Liouville mode of the supercritical string. In this scenario the Friedmann equation receives additional contributions due to the non-criticality of the string. These are potentially important when one seeks to apply the Bousso bound for the entropy of states that may become light as the dilaton takes on trans-Planckian values, as in a de Sitter phase, and restore consistency with the FSC and in at least some cases also the SSC. The weak gravity conjecture (WGC) for scalar potentials is saturated in the supercritical string scenarios discussed in this work, but only if one uses the dilaton as appears in the string effective action, with a kinetic term that is not canonically normalised. In the case of a non-critical Starobinsky potential, the WGC is satisfied by both the canonically-normalised dilaton and the dilaton used in the string effective action.
