摘要

在本文中，我们研究了一个耦合波方程系统，该系统的特点是对部分域施加边界分数阻尼。我们首先建立了该系统的良好拟合性，并通过半群理论证明了解的存在性和唯一性。虽然该系统没有表现出指数稳定性，但我们证明了其强大的稳定性。此外，利用阿伦特和巴蒂的一般标准以及某些几何条件，我们证明了解的多项式能量衰减率。

Polynomial decay of the energy of solutions of coupled wave equations with locally boundary fractional dissipation

In this paper, we investigate a system of coupled wave equations featuring boundary fractional damping applied to a portion of the domain. We first establish the well-posedness of the system, proving the existence and uniqueness of solutions through semi-group theory. While the system does not exhibit exponential stability, we demonstrate its strong stability. Furthermore, leveraging Arendt and Batty’s general criteria and certain geometric conditions, we prove a polynomial rate of energy decay for the solutions.
