引力波记忆和它的电磁模拟被证明是波动方程的直接结果。从麦克斯韦方程可以得到电场的波动方程,而从比安奇恒等式可以得到线性化重力中黎曼张量的波动方程。在这两种情况下的记忆都是从这些波动方程的源的结构中得出的。
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.
