Instability of type II blow up for the quintic nonlinear wave equation on $\mathbb{R}^{3+1}$

Joachim Krieger, Joules Elie Nahas

We prove that the blow up solutions of type II character constructed by Krieger-Schlag-Tataru [21] as well as Krieger-Schlag [20] are unstable in the energy topology in that there exist open data sets whose closure contains the dataof the preceding type II ...
