报告摘要： In this talk, we study the uniform robustness of pullback attractors for non-autonomous dynamical systems with delayed parameter. We establish two theoretical results: (1) Uniformly upper semi-continuity of pullback attractors in the initial value space as delayed parameter tends to zero; (2) Uniformly upper semi-continuity of pullback attractors in the regular space. Moreover, we apply the above two theoretical results to non-autonomous time-delayed reaction-diffusion equations defined on bounded domains and unbounded domains, respectively.
