摘要
考虑具有线性记忆和线性阻尼的Kirchhoff梁方程的指数吸引子.首先,用能量估计方法给出强弱空间中的有界吸收集;其次,用算子分解方法在弱拓扑空间中证明具有线性记忆项和线性阻尼项的Kirchhoff型梁方程指数吸引子的存在性.
We considered exponential attractor of Kirchhoff beam equation with linear memory and linear damping.Firstly,we gave the bounded absorbing sets in the strong-weak space by using the method of energy estimation.Secondly,we proved the existence of exponential attractors for Kirchhoff type beam equations with linear memory term and linear damping term in weak topological space by using the method of operator decomposition.
