论文摘要
我们表明，可以通过图形方法通过源图从Glauber-Sudarshan State的路径积分表示，使用示意图进行了四维DE Sitter空间的明确构造。这些图的总和通常会导致一系列渐近的gevrey类型，然后可以重新定位borel，从而重现系统的非扰动结构。我们的分析表明，在克服不进行的弦理论中，不仅可以使用四维保安空间，尽管它是格劳伯 - 苏迪尔山的状态，但它也可能在受控的时间域内稳定。在某种程度上，Gevrey系列的Borel重新调整为宇宙常数的积极性提供了强烈的暗示。
We show that an explicit construction of a four-dimensional de Sitter space may be performed using a diagrammatic approach via nodal diagrams emanating from the path integral representation of the Glauber-Sudarshan state. Sum of these diagrams typically leads to an asymptotic series of Gevrey kind which can then be Borel resummed, thus reproducing the non-perturbative structure of the system. Our analysis shows that four-dimensional de Sitter space is not only possible in string theory overcoming the no-go and the swampland criteria -- albeit as a Glauber-Sudarshan state -- but it may also be non-perturbatively stable within a controlled temporal domain. Somewhat consistently, the Borel resummation of the Gevrey series provides strong hint towards the positivity of the cosmological constant.
