隐藏对称与黑洞

Hidden Symmetries and Black Holes

Valeri P. Frolov

摘要:

本文简要回顾了近年来关于高维黑洞时空中隐对称性的研究结果。我们展示了如何存在的主要CKY张量(这是一个封闭的共形Killing-Yano 2-形式)允许一个“塔”的Killing-Yano和Killing张量负责隐藏的对称性。这些对称性意味着在广义Kerr-NUT-(A)dS度规下,Hamilton-Jacobi、Klein-Gordon、Dirac和引力摄动方程中测地线方程的完全可积性和变量的完全分离性。在这些时空中,沿着测地线的平行坐标系输运方程也是可积的。

英文摘要:

The paper contains a brief review of recent results on hidden symmetries in higher dimensional black hole spacetimes. We show how the existence of a principal CKY tensor (that is a closed conformal Killing-Yano 2-form) allows one to generate a `tower' of Killing-Yano and Killing tensors responsible for hidden symmetries. These symmetries imply complete integrability of geodesic equations and the complete separation of variables in the Hamilton-Jacobi, Klein-Gordon, Dirac and gravitational perturbation equations in the general Kerr-NUT-(A)dS metrics. Equations of the parallel transport of frames along geodesics in these spacetimes are also integrable.
