Maths HEP Lunchtime Seminars: Aretakis charges and null infinity

Presented by Mahdi Godazgar, Zurich, ETH
9 February 2018 13:00 in CM101

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.
