Pullback attractors for the higher-order Kirchhoff-type equation with time delay
摘要:
研究了带有时滞项的高阶Kirchhoff方程的拉回吸引子的存在性.首先利用解的有界性验证了拉回吸引集的存在性,接着借助sobolev空间的紧嵌入证明了该初边值问题产生的过程是紧的,最后得到了拉回吸引子的存在性.
In this paper,we deal with the existence of pullback attractor for the higher-order Kirchhoff-type equation with time delay.Firstly,the existence of pullback absorbing set is verified by the boundedness of the solution,then the compact embedding for the sobolev space allows us to prove the compactness of the process produced by the initial value problem.At last,we get the existence of the pullback attractor.
