Mode stability of blow-up for wave maps in the absence of symmetry
Max Weissenbacher, Herbert Koch, Roland Donninger
The wave maps equation in three spatial dimensions with a spherical target admits an explicit blow-up solution. Numerical studies suggest this solution captures the generic blow-up…

Decay and non-decay for the massless Vlasov equation on subextremal and extremal Reissner-Nordström black holes
Max Weissenbacher
We study the massless Vlasov equation on the exterior of the subextremal and extremal Reissner-Nordström spacetimes. We prove that moments decay at an exponential rate in the sube…
