论文摘要
虽然位于DE Sitter（DS）空间中的静态观察者检测到地平线发出的热辐射，但DS异构体迫使辐射与背景保持平衡。这意味着要使静态观察者找到信息悖论，必须将背景变形为quasi-ds空间，在该空间中，在该空间中，在该空间中，DS异构体自发折断。我们研究了信息悖论在准DS空间中产生的条件，其单调增加的地平面大小用于描述通货膨胀宇宙学。为此，考虑了三维DS空间的尺寸减小，该空间具有由JT重力建模的热辐射与CFT结合的。我们认为，当中央电荷在时间上单调增加时，就会出现信息悖论，但是岛上存在的条件变得更加限制。由于中心电荷可以解释为自由度的数量，因此，准DS空间中没有岛屿支持DS Swampland猜想的熵论证。
Whereas a static observer in de Sitter (dS) space detects thermal radiation emitted by the horizon, the dS isometries impose that the radiation is in equilibrium with the background. This implies that for the static observer to find the information paradox, the background must be deformed to quasi-dS space in which the dS isometries are spontaneously broken. We study the condition that the information paradox arises in quasi-dS space with the monotonically increasing horizon size which is used to describe the inflationary cosmology. For this purpose, the dimensional reduction of three-dimensional dS space with thermal radiation modelled by the JT gravity coupled to CFT is considered. We argue that when the central charge monotonically increases in time, the information paradox arises but the conditions for the existence of the island become more restrictive. As the central charge can be interpreted as the number of degrees of freedom, the absence of the island in quasi-dS space supports the entropy argument for the dS swampland conjecture.
