具混合变元的二阶拟线性阻尼wave equations的振动性

Oscillation of damped second order quasilinear wave equations with mixed arguments

Ying Sui, Huimin Yu

摘要:

在文献[1]的基础上,我们研究了阻尼对一类具有Robin和Dirichlet边界条件的拟线性波动方程光滑解振动性的影响.利用广义Riccati变换和技术不等式方法,给出了保证所有光滑解振动的若干充分条件。结果表明,正阻尼可以“抑制”振荡。最后,给出了一些例子来证实我们的主要结果。

英文摘要:

Following the previous work [1], we investigate the impact of damping on the oscillation of smooth solutions to some kind of quasilinear wave equations with Robin and Dirichlet boundary condition. By using generalized Riccati transformation and technical inequality method, we give some sufficient conditions to guarantee the oscillation of all smooth solutions. From the results, we conclude that positive damping can ``hold back" oscillation. At last, some examples are presented to confirm our main results.
