在本文中,我们讨论了时间周期耗散项对耗散波方程解的先验估计的影响。该方法基于高频的对角化论证和周期微分方程谱理论/有界频率的弗洛奎特理论的结果。
In this short note we discuss the influence of a time-periodic dissipation term on a-priori estimates for solutions to dissipative wave equations. The approach is based on a diagonalisation argument for high frequencies and results from spectral theory of periodic differential equations / Floquet theory for bounded frequencies.
