A note on the null condition for quadratic nonlinear Klein-Gordon systems in two space dimensions
Soichiro Katayama, Tohru Ozawa, Hideaki Sunagawa
We consider the Cauchy problem for quadratic nonlinear Klein-Gordon systems in two space dimensions with masses satisfying the resonance relation. Under the null condition in the s…

Global small amplitude solutions for two-dimensional nonlinear Klein-Gordon systems in the presence of mass resonance
Yuichiro Kawahara, Hideaki Sunagawa
We consider a nonlinear system of two-dimensional Klein-Gordon equations with masses satisfying the resonance relation. We introduce a structural condition on the nonlinearities un…
