AI总结:

本文通过dS$_3$/CFT$_2$对应研究dS$_3$引力的黑洞解,利用Liouville关联函数分类允许的复几何,并推广至高自旋引力情形。

摘要:

我们通过显式的dS$_3$/CFT$_2$对应来研究dS$_3$引力的黑洞解。该引力理论由具有复规范群SL$(2,\mathbb{C})$的Chern-Simons理论描述,已知复化理论有过多鞍点。我们从对偶CFT关联函数中确定“允许几何”的集合。具体而言,我们从Liouville两点函数出发,对对应于dS$_3$黑洞的可能复解进行分类。我们将分析扩展到Liouville多点函数,并特别研究了由Liouville四点函数的单值矩阵对应的$S^3$上两个相连Wilson环的几何。部分结果已在先前的一封信中给出,但此处对其进行了更详细的解释并以多种方式进行了扩展。特别是,我们通过关注高自旋荷的效应,将结果推广到高自旋引力情形。

英文摘要:

We examine the black hole solutions of dS$_3$ gravity by applying the explicit dS$_3$/CFT$_2$ correspondence. The gravity theory is described by Chern-Simons theory with complex gauge group SL$(2,\mathbb{C})$, and the complexified theory is known to have too many saddle points. We determine the set of "allowable geometry" from dual CFT correlators. Concretely, we classify the possible complex solutions corresponding to dS$_3$ black holes from Liouville two-point functions. We extend the analysis to Liouville multi-point functions and among others we study geometry corresponding to two linked Wilson loops on $S^3$ by the monodromy matrix of Liouville four-point function. Some parts of the results were presented in a previous letter but here they are explained in more details and extended in various ways. In particular, we generalize the results to the case with higher-spin gravity by focusing the effects of higher-spin charges.
