论文摘要
本文的目的是研究具有非平滑局部粘弹性阻尼的一维耦合波方程的稳定,开尔文 - 沃伊格特类型和局部时间延迟。使用Arendt-Batty的一般标准,我们在没有解决方案的紧凑性的情况下显示了系统的强稳定性。最后,使用频域方法与乘数方法结合使用,我们证明了1/t的多项式能量衰减速率。
The purpose of this paper is to investigate the stabilization of a one-dimensional coupled wave equations with non smooth localized viscoelastic damping of Kelvin-Voigt type and localized time delay. Using a general criteria of Arendt-Batty, we show the strong stability of our system in the absence of the compactness of the resolvent. Finally, using frequency domain approach combining with a multiplier method, we prove a polynomial energy decay rate of order 1/t.
