Scattering for defocusing energy subcritical nonlinear wave equations

Benjamin Dodson, Andrew Lawrie, Dana Mendelson and Jason Murphy

Vol. 13 (2020), No. 7, 1995–2090

We consider the Cauchy problem for the defocusing power-type nonlinear wave equation in (1+ 3)-dimensions for energy subcritical powers p in the superconformal range 3 < p < 5. We prove that any solution is global-in-time and scatters to free waves in both time directions as long as its critical Sobolev norm stays bounded on the maximal interval of existence.
