论文摘要
引力波记忆及其电磁类似物被证明是波方程的简单后果。从麦克斯韦的方程式可以得出电场的波方程，而从比安奇身份则可以在线性化重力中得出Riemann张量的波方程。在这两种情况下，记忆均来自这些波动方程源的结构。
Gravitational wave memory and its electromagnetic analog are shown to be straightforward consequences of the wave equation. From Maxwell's equations one can derive a wave equation for the electric field, while from the Bianchi identity one can derive a wave equation for the Riemann tensor in linearized gravity. Memory in both cases is derived from the structure of the source of those wave equations.
