一类弱耗散Bresse系统的多项式和非指数稳定性

Polynomial and non exponential stability of a weak dissipative Bresse system

Aissa Guesmia

摘要:

本文研究了有界区域上线性摩擦耗散仅作用于实位移的Bresse系统。纵向和剪切角位移是自由的。我们的第一个主要结果是证明,独立于波的传播速度,这种线性摩擦耗散不稳定指数整个Bresse系统。我们的第二个主要结果是表明,解决方案收敛到零至少多项式。我们的系统的适定性的证明是基于半群理论。将使用能量法和频域方法的组合来证明稳定性结果。

英文摘要:

In this paper, we study the Bresse system in a bounded domain with linear frictional dissipation working only on the veridical displacement. The longitudinal and shear angle displacements are free. Our first main result is to prove that, independently from the velocities of waves propagations, this linear frictional dissipation does not stabilize exponentially the whole Bresse system. Our second main result is to show that the solution converges to zero at least polynomially. The proof of the well-posedness of our system is based on the semigroup theory. The stability results will be proved using a combination of the energy method and the frequency domain approach.
