我们从引力反常的角度研究了旋转黑洞的霍金辐射。首先，我们证明了克尔黑洞视界附近的标量场理论可以归结为二维有效理论。然后，在Robinson和Wilczek之后，我们通过要求抵消引力反常来得到霍金通量。我们还将该方法应用于高维Myers-Perry黑洞的Hawking辐射。在附录中，我们给出了霍金辐射的迹线异常的推导，以论证边界条件在视界的有效性。
We study the Hawking radiation from Rotating black holes from the gravitational anomalies point of view. First, we show that the scalar field theory near the Kerr black hole horizon can be reduced to the 2-dimensional effective theory. Then, following Robinson and Wilczek, we derive the Hawking flux by requiring the cancellation of gravitational anomalies. We also apply this method to Hawking radiation from higher dimensional Myers-Perry black holes. In the appendix, we present the trace anomaly derivation of Hawking radiation to argue the validity of the boundary condition at the horizon.
