论文摘要
我们表明，与一般相对性的内部洛伦兹对称性相关的电荷，动作中包含较高的导数边界项，捕获可观察到的引力波效应。特别是，高斯河网电荷测量了自由垂直陀螺仪的进动率，而Pontryagin电荷编码自由掉落测试质量的相对径向加速度。这种关系强调了四局形式主义的重要性以及渐近内部洛伦兹对称性的物理意义。
We show that charges associated with the internal Lorentz symmetries of general relativity, with higher derivative boundary terms included in the action, capture observable gravitational wave effects. In particular, the Gauss-Bonnet charge measures the precession rate of a freely-falling gyroscope, while the Pontryagin charge encodes the relative radial acceleration of freely-falling test masses. This relation highlights the importance of the tetrad formalism and the physical significance of asymptotic internal Lorentz symmetries.
