二维二次非线性Klein-Gordon系统零条件的注记

A note on the null condition for quadratic nonlinear Klein-Gordon systems in two space dimensions

Soichiro Katayama, Tohru Ozawa, Hideaki Sunagawa

摘要:

本文考虑二维空间中质量满足共振关系的二次非线性Klein-Gordon系统的Cauchy问题。在零条件下,在J. - M. Delort,D.方河,巴西-地Xue(2004),我们证明了当初始值足够小时,在加权索伯列夫空间中渐近自由解的整体存在性.我们的证明是基于满足零条件的非线性代数特征。

英文摘要:

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 sense of J.-M. Delort, D. Fang, R. Xue (2004), we show the global existence of asymptotically free solutions if the initial data are sufficiently small in some weighted Sobolev space. Our proof is based on an algebraic characterization of nonlinearities satisfying the null condition.
