Seminarium KMMF "Teoria Dwoistości"

The theoretical description of gravitational waves has become very important in recent years due to relevant past and future experiments. One way to describe gravitational radiation is by studying the asymptotic symmetries of spacetimes. In my talk, I will briefly introduce the asymptotically flat spacetimes and present the BMS group as the group of transformations preserving the asymptotic form of the metric. Then, I will show how these transformations may be used to describe the gravitational memory effect.
