活动内容摘要：

We consider the boundary stabilization for wave equations with dynamic boundary conditions. By spectrum method, there exists a solution whose energy decays with arbitrary slow rates.  Making some elaborate and subtle analysis of an associated auxiliary system, we obtain an estimate of the resolvent of the generator of the system along the imaginary axis. This enables us to prove that the solution energies of the system with high regularity initial value decay polynomially.
