Abstract:

In this paper, we consider the weakly damped wave equations with delays and sup-cubic nonlinearity. We prove the existence of the uniform attractors in $C_{H_{0}^{1}(\Omega)}\times C_{L^{2}(\Omega)}$ by constructing the energy functional and combining with the idea of contractive functions..

Key words: Weakly damped wave equations, Delays, Uniform attractors
