带力和力矩反馈的传递Euler-Bernoulli板方程的弱镇定

Weak stabilization of a transmission Euler-Bernoulli plate equation with force and moment feedback

Fathi Hassine

摘要:

本文研究具有力和力矩反馈的透射板方程能量衰减的渐近性态。确切地说,我们将证明能量至少随时间以几何学的方式衰减。该方法是利用经典的二阶Carleman估计建立预解估计,该预解估计由著名的Burq结果[Bur 98]提供上述衰减类型。

英文摘要:

In this paper we will study the asymptotic behaviour of the energy decay of a transmission plate equation with force and moment feedback. Precisly, we shall prove that the energy decay at least logarithmically over the time. The method consist to use the classical second order Carleman estimate to estabish a resolvent estimate which provide by the famous Burq's result [Bur98] the kind of decay above mentionned.
