Global Solutions of Multispeed Semilinear Klein-Gordon Systems in Space Dimension Two

Xilu Zhu

AI总结:

该研究针对二维空间带非退化条件的半线性多速度Klein-Gordon系统,在傅里叶侧分析时空共振邻域贡献,证明小初值下解全局存在且散射到线性解,部分推广了Deng的三维拟线性结果。

摘要:

我们研究满足若干非退化条件的二维空间一般半线性多速度Klein-Gordon系统。证明了当初始数据较小时,这类系统的解始终是全局的,且会散射到一个线性解。该结果部分推广了Deng此前完全证明三维拟线性情形的成果。证明主要在傅里叶侧展开,探究时空共振邻域的贡献。

英文摘要:

We consider general semilinear, multispeed Klein-Gordon systems in space dimension two with some non-degeneracy conditions. We prove that with small initial data such solutions are always global and scatter to a linear solution. This result partly extends the previous result obtained by Deng, who completely proved the 3D quasilinear case. To prove our result, we mainly work on Fourier side and explore the contribution from the vicinity of space-time resonaonce.
