论文摘要
我们为Lorentz提升和旋转提出了一个明确的公式,该公式在渐近平坦的空间中与BMS超斜线通勤。构建的关键是使用红外正规化和统一转换,使可观察到的自由度通勤。我们明确验证了我们的费用是否满足Lorentz代数,我们检查它们是否通过在超级翻译的Minkowski空间和增强的Kerr Black Hole上评估它们与期望一致。
We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of infrared regularizations and of a unitary transformation that makes observables commute with the soft degrees of freedom. We explicitly verify that our charges satisfy the Lorentz algebra and we check that they are consistent with expectations by evaluating them on the supertranslated Minkowski space and on the boosted Kerr black hole.
