Mohammad Akil, Haidar Badawi, Serge Nicaise

摘要:

本文研究了具有局部Kelvin-Voigt阻尼/阻尼的局部耦合波方程的直接/间接稳定性,并假设阻尼的支撑和耦合系数是不相交的。首先,我们证明了某些一维耦合系统的适定性、强稳定性和多项式稳定性。在一定的几何控制条件下,证明了多维情形下的适定性和强稳定性。

英文摘要:

In this paper, we study the direct/indirect stability of locally coupled wave equations with local Kelvin-Voigt dampings/damping and by assuming that the supports of the dampings and the coupling coefficients are disjoint. First, we prove the well-posedness, strong stability, and polynomial stability for some one dimensional coupled systems. Moreover, under some geometric control condition, we prove the well-posedness and strong stability in the multi-dimensional case.
