时滞半线性波动型方程的适定性与稳定性

Well-posedness and stability for semilinear wave-type equations with time delay

Alessandro Paolucci, Cristina Pignotti

摘要:

本文研究了一类具有时滞的半线性抽象阻尼波型方程。我们假设时滞反馈系数是随时间变化的,并且属于$L^1_{loc}([0, +\infty)).$。在适当的假设下,我们证明了小初始数据下的适定性和指数稳定性。我们的策略结合了仔细的能量估计和连续性参数。一些例子说明了抽象的结果。

英文摘要:

In this paper we analyze a semilinear abstract damped wave-type equation with time delay. We assume that the delay feedback coefficient is variable in time and belonging to $L^1_{loc}([0, +\infty)).$ Under suitable assumptions, we show well-posedness and exponential stability for small initial data. Our strategy combines careful energy estimates and continuity arguments. Some examples illustrate the abstract results.
