We reexamine the Israel-type proof of the uniqueness theorem of the static spacetime outside the photon surface in the Einstein-conformal scalar system. We derive in a systematic fashion a new divergence identity which plays a key role in the proof. Our divergence identity includes three parameters, allowing us to give a new proof of the uniqueness.

具有共形标量头发的静态时空的发散方程和唯一性定理

我们重新研究了爱因斯坦共形标量系统中光子表面外静态时空唯一性定理的以色列式证明。我们以系统的方式推导出一个新的分歧恒等式,它在证明中起关键作用。我们的分歧身份包括三个参数,使我们能够提供唯一性的新证明。
