摘要：In this talk, we discuss “ODE-type” singularity formation for the focusing power nonlinearity wave ☐Φ= -Φp, for any power and any spacetime dimension. We show that, for any smooth spacelike hypersurface, one can find a smooth solution that blows up precisely at that hypersurface, and moreover the location of this blow up surface is stable to perturbations of data away from the singularity. Joint with Istvan Kadar (ETH Zurich).
