摘要
运用非自治无穷维动力系统中的拉回吸引子理论,结合压缩函数和能量估计的方法,研究了带有时间依赖系数的非自治基尔霍夫型吊桥方程拉回吸引子的存在性.
In this paper,based on the theorem of pullback attractors for non-autonomous infinite dimensional dynamical systems,combining with the contractive functions and energy estimates,the exi-stence of the pullback attractors for non-autonomous Kirchhoff-type suspension bridge equations with time-dependent coefficient is studied.
