论文摘要
布兰斯 - 迪克理论中存在重力记忆效应。它们与孤立系统中的无限无穷大的Bondi-Metzner-Sachs对称性密切相关。通过研究Brans-Dicke理论和渐近对称性的渐近时空，人们发现张量扇形的位移记忆效应是由于无效的无效无穷大属性引起的真空过渡引起的，而在标量部门，真空过渡归因于恒星过渡，构成了象征。连同自旋和质量内存效应，位移记忆受到各种磁通平衡法的限制。
There exist gravitational memory effects in Brans-Dicke theory. They are closely related to the Bondi-Metzner-Sachs symmetries living on the null infinity in an isolated system. By studying the asymptotically flat spacetime in Brans-Dicke theory and the asymptotic symmetries, one discovers that the displacement memory effect in the tensor sector is due to the vacuum transition caused by the null energy fluxes panetrating the null infinity, while in the scalar sector, the vacuum transition is due to the angular momentum fluxes. Together with the spin and the center-of-mass memory effects, the displacement memories are constrained by various flux-balance laws.
