摘要:

该文考虑带有时滞项的弱阻尼波方程一致吸引子的存在性,其中非线性项的增长次数大于3而小于5.通过构造能量泛函并结合收缩函数方法得到过程$U_{g}(t, \tau)$$g\in{\cal H}(g_{0})$$C_{H^{1}_{0}(\Omega)}\times C_{L^{2}(\Omega)}$中一致吸引子的存在性.

关键词: 弱阻尼波方程, 时滞, 一致吸引子

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
