论文摘要
我们表明，与Kerr/CFT对应关系相关的隐藏保形对称性的研究也可以应用于Kerr-Newman-Taub-nut-De Sitter Spacetime中的宇宙学范围。这种对称性使人们可以采用二维形式的磁场理论方法来了解宇宙学范围的特性。可以通过使用Cardy公式来理解熵，并且在近区域中的散射过程方程与从二维形式的保形场理论中获得的散射过程一致。我们还表明，在近乎极端条件下，Kerr-Newman-Taub-Nut-De保姆的宇宙学范围内可能发生对生产。
We show that the study of hidden conformal symmetry that associates to the Kerr/CFT correspondence can also apply to the cosmological horizon in Kerr-Newman-Taub-NUT-de Sitter spacetime. This symmetry allows one to employ some two dimensional conformal field theory methods to understand the properties of the cosmological horizon. The entropy can be understood by using the Cardy formula, and the equation for scattering process in the near region has an agreement with the one obtained from a two point function in two dimensional conformal field theory. We also show that pair production can occur near the cosmological horizon in Kerr-Newman-Taub-NUT-de Sitter for near extremal conditions.
