We present a systematic construction of the Penrose coordinates and plane wave limits of spacetimes for which both the null Hamilton–Jacobi and geodesic equations separate. The method is applied to Kerr-NUT-(A)dS four-dimensional black holes. The plane wave limits of the near horizon geometry of the extreme Kerr black hole are also explored. All near horizon geometries of extreme black holes with a regular Killing horizon admit Minkowski spacetime as a plane wave limit.

可分离性、平面波极限和旋转黑洞

我们提出了彭罗斯坐标和时空平面波极限的系统构造,其中零哈密尔顿-雅可比方程和测地线方程都分开了。该方法应用于Kerr-NUT-(A)dS 四维黑洞。还探索了极端克尔黑洞的近视界几何的平面波极限。所有具有规则杀戮视界的极端黑洞的近视界几何都承认闵可夫斯基时空是平面波的极限。
