Pieter Blue - Decay for fields outside black holes

- niveau 1 niveau 2 niveau 3
Descriptif
I will discuss energy and Morawetz (or integrated local decay) estimates for fields outside black holes. These results build on results for the wave equation and use the Killing tensor, an unusual geometric object that exists in the Kerr spacetime.
