Kerr-de Sitter灰体因子的等值线法

Kerr-de Sitter Greybody Factors via Isomonodromy

Bruno Carneiro da Cunha, Fábio Novaes

摘要:

散射数据一般可以用单值性来描述。本文利用这种单值技术得到了Kerr-de Sitter黑洞中共形耦合标量场的散射振幅。唯一的非平凡参数,两个正则奇点之间的复合单值参数$σ_{ij}$,可以根据Painlevé VI $τ$ -函数隐式地求解。应用Virasoro共形块来解决后者,现在可以解释为共形对称性和黑洞之间惊人关系的验证。

英文摘要:

Scattering data can be generically described in terms of monodromies. Here we obtain scattering amplitudes for conformally coupled scalar fields in Kerr-de Sitter black holes using this monodromy technique. The only non-trivial parameter, the composite monodromy parameter $σ_{ij}$ between two regular singular points, can be solved implicitily in terms of the Painlevé VI $τ$-function. The application of the Virasoro conformal blocks to solve the latter can now be interpreted as a verification of the striking relationship between conformal symmetry and black holes.
