Global attractor of the weakly damped wave equation with nonlinear boundary conditions
Chaosheng Zhu
Southwest University
In this paper, the main purpose is to study existence of the global attractors for the weakly damped wave equation with nonlinear boundary conditions. To this end, we first show that the existence of a bounded absorbing set by the perturbed energy method. Secondly, we utilize the decomposition of the solution operator to verify the asymptotic compactness.
Keywords: wave equation, nonlinear boundary conditions, global attractor
