The existence of pullback \mathcalD - attractors for a non-autonomous Kirchhoff-type plate equation

  • 摘要: 研究具有线性记忆项和结构阻尼的非自治Kirchhoff型板方程拉回 \mathcalD - 吸引子的存在性. 为此, 引入了一个新的变量 \eta , 通过将先验估计和收缩函数相结合的方法, 证明了拉回吸收集和拉回渐近紧性, 最终得到了拉回 \mathcalD - 吸引子的存在性.

     

    Abstract: We try to study the pullback \mathcalD - attractors for the non-autonomous Kirchhoff-type plate equation with linear memory and structural damping. Consequently, we introduce a new variable \eta , and prove the pullback absorption set and asymptotic compactness by combining the prior estimate with the contraction function. Ultimately, we obtain the existence of the pullback \mathcalD - attractors.
