恒元物理学讲座（第101期）： Soft theorems, memories and asymptotic symmetries

讲座内容：Soft theorems, memory effects, and asymptotic symmetries are shownin recent years to be mathematically equivalent. In this talk, I will give anoverview of this fascinating triangle equivalence. In particular, I willexplain in detail a very recent prescription to realize this triangle relationbeyond the leading order. I will also comment on the extension of this trianglerelation in arbitrary even dimensions.
