Umberto Biccari, Sorin Micu

摘要:

研究了一维环面$\mathbb{T}=\mathbb{R}/2π\mathbb{Z}$上一类主部具有记忆的波动方程的内能控性。我们假设控制作用在一个开子集$ω(t)\subset\mathbb{T}$上,它以恒定速度$c\in\mathbb{R}\setminus\{-1,0,1\}$运动。本文的主要结果表明,在足够长的时间$T$内,当初始数据属于合适的索伯列夫空间时,该方程是零能控的.它的证明如下仔细分析的频谱相关的问题,并从应用程序的经典矩法。

英文摘要:

We study the internal controllability of a wave equation with memory in the principal part, defined on the one-dimensional torus $\mathbb{T}=\mathbb{R}/2π\mathbb{Z}$. We assume that the control is acting on an open subset $ω(t)\subset\mathbb{T}$, which is moving with a constant velocity $c\in\mathbb{R}\setminus\{-1,0,1\}$. The main result of the paper shows that the equation is null controllable in a sufficiently large time $T$ and for initial data belonging to suitable Sobolev spaces. Its proof follows from a careful analysis of the spectrum associated to our problem and from the application of the classical moment method.
