摘要
讨论了非自治梁方程的长时间动力学行为,通过应用一些新的结果和能量估计技巧,获得了能量的一致衰退估计,当外力项h满足条件(C*)(而非平移紧)时,证明了一致吸引子在H10(Ω)×L2(Ω)上的存在性,此结果推广和改进了一些已有结果。
The long-time dynamical behavior of the non-autonomous beam equation is discussed.On the basis of some new results and technique of energy estimates,the uniformly decay estimate is obtained.When forcing term h only satisfies Condition (C *) instead of translation compact,the existence of uniform attractors in H01 (Ω) × L2 (Ω) is proven.The result extends and improves some known results.
