报告题目：Robust attractors for a perturbed non-autonomous extensiblebeam equation with nonlinear nonlocal damping

报告摘要：In this talk, we investigates the attractors and their robustness for a perturbed non-autonomous extensiblebeam equation with nonlinear nonlocal damping. We prove that the related evolution process has a finite dimensionalpullback attractor A_\kappa and a pullback exponential attractor M_{exp}^\kappa for each extensibility parameter \kappa\in[0; 1] , respectively, and both of them are stable on the perturbation \kappa . In particular, these stability holds for the global and exponential attractors when the non-autonomous dynamical system degenerates to an autonomous one, so these results deepen and extend those in recent literatures.
