本文考虑带有非线性阻尼项的非线性发展方程解的长时间行为.基于时间依赖空间中的吸引子理论,本文利用压缩函数方法和一些估计技巧证明了带有临界非线性项的非线性发展方程时间依赖吸引子的存在性.
In this paper, we consider long-time behavior of solutions for the nonlinear evolution equation with nonlinear damping. With the theory of process on time-dependent spaces and some detailed esti- mates, we prove the existence of the time-dependent attractor for the nonlinear evolution equation with critical nonlinearity by using the Contractive functions.
