Global existence of solutions of a loglog energy-supercritical Klein-Gordon equation
arXiv:2101.03248
Abstract
We prove global existence of solutions of a loglog energy-supercritical Klein-Gordon equation for n=3,4,5. Assuming that blow-up occurs at a time of maximal existence, we perform an analysis close to this time in order to find a finite bound of a Strichartz-type norm, which eventually leads to a contraction with the blow-up assumption.
