Blow up for critical wave equations on curved backgrounds
arXiv:1303.1967
Abstract
We extend the slow blow up solutions of Krieger, Schlag, and Tataru to semilinear wave equations on a curved background. In particular, for a class of manifolds we show the existence of a family of blow-up solutions with finite energy norm to the equation {equation} \partial_t^2 u - Δ_g u = |u|^4 u, \notag {equation} with a continuous rate of blow up. In contrast to the case where is the Minkowski metric, the argument used to produce these solutions can only obtain blow up rates that are bounded above.
