论文摘要
在本文中,我们在紧凑型谎言组上研究了具有较低阶段(阻尼和质量)以及功率类型的非线性$ | u |^p $的半线性波方程。我们将证明在Evolution Energy空间中的小型数据解决方案的全球时间存在,而无需$ p> 1 $的任何下限。在我们的方法中,我们对紧凑型谎言组的傅立叶分析采用了一些结果。
In this paper, we study the semilinear wave equation with lower order terms (damping and mass) and with power type nonlinearity $|u|^p$ on compact Lie groups. We will prove the global in time existence of small data solutions in the evolution energy space without requiring any lower bounds for $p>1$. In our approach, we employ some results from Fourier analysis on compact Lie groups.
