Scattering of rough solutions of the nonlinear Klein-Gordon equations in 3D

arXiv:1008.0094

Abstract

We prove scattering of solutions below the energy norm of the 3D Klein-Gordon equation for 5>p>3. In order to do that, we generate an exponential-type decay estimate in H^{s}, s<1, by means of concentration and a low-high frequency decomposition.
