研究了一类具有退化非局部强阻尼的Kirchhoff型梁方程解的存在唯一性, 全局吸引子与强全局吸引子的存在性. 首先,应用Faedo-Galerkin逼近和插值不等式证明了弱解的存在唯一性;其次,通过构造有界吸收集,证明解半群的渐近紧性,从而得到系统在拓扑空间

存在全局吸引子;最后利用范数到弱连续半群理论和条件(C),证明了系统在强拓扑空间

存在全局吸引子.
The existence and uniqueness of solutions,as well as the existence of global attractors and strong global attractors are investigated for a class of Kirchhoff-type beam equations with degenerate nonlocal strong damping. Firstly, we establish the existence and uniqueness of weak solutions by employing the Faedo-Galerkin approximation along with interpolation inequalities. Secondly, by constructing a bounded absorbing set,we establish the asymptot
ic compactness of the solution semigroup, and thereby obtain the existence of a global attractor in the topological space

. Finally, we apply the norm-to-weak continuous semigroup theory and condition (C), to show that the system also has a global attractor in the stronger topological space
