Scattering for the quadratic Klein-Gordon equations
Zihua Guo, Jia Shen
We study the scattering problems for the quadratic Klein-Gordon equations with radial initial data in the energy space. For 3D, we prove small data scattering, and for 4D, we prove…

Scattering below the ground state for the 2D non-linear Schrödinger and Klein-Gordon equations revisited
Zihua Guo, Jia Shen
We revisit the scattering problems for the 2D mass super-critical Schrödinger and Klein-Gordon equations with radial data below the ground state in the energy space. We give an alt…
