In this talk, I will give an extended introduction on asymptotic symmetries in gauge theories and gravity, and discuss their importance.
Then I focus on asymptotically flat spacetimes in 4 dimensions and introduce BMS symmetries. Finally I discuss how the conservation laws associated with BMS symmetries can be used to study gravitational waves. |
