Description
I will discuss the construction of the orbits of Minkowski and Schwarzschild black hole under the group of asymptotic symmetries of flat spacetimes, namely the BMS group. I will discuss the possible relevance of these solutions to gravitational collapse thanks to infinite dimensional classical conservation laws. In particular, I will explain the special role of superrotation charges. I will contrast the results with the ones of Hawking-Perry-Strominger.
