Aretakis charges and their relation to Newman-Penrose charges:

02.11.2017 14:00 – 15:00

I will describe a recent discovery of conserved charges on the horizon of extremal black holes, which leads in particular to their classical dynamical instability. I will then relate these somewhat unexpected charges to the very well-understood Newman-Penrose charges at the null infinity of asymptotically flat spaces.
