半线性阻尼wave equation方程解的指数衰减

Exponential decay for solutions to semilinear damped wave equation

Stéphane Gerbi, Belkacem Said-Houari

摘要:

研究了有界区域上具有强阻尼项的半线性波动方程解的衰减估计。引入适当的Lyaponuv函数,我们证明了当阻尼是线性的,我们可以找到初始数据,对于它的解指数衰减。这个结果改进了Gazzola和Squassina的文章中的早期结果。

英文摘要:

This paper is concerned with decay estimate of solutions to the semilinear wave equation with strong damping in a bounded domain. Introducing an appropriate Lyaponuv function, we prove that when the damping is linear, we can find initial data, for which the solution decays exponentially. This result improves an early one in an article of Gazzola and Squassina.
