摘要：

We show that the static tidal Love number of Schwarzschild black holes in four dimensions and in the vacuum vanishes at any order in a parity-even external tidal force. We also identify the underlying non-linear symmetry which is responsible for this result and becomes manifest when the black hole metric is written in axsymmetric static Weyl coordinates.
