报告题目:Continuity ofpullback random attractors for nonautonomous cocycles
报告摘要:In this talk, we focus on the continuity of pullback random attractors, where the parameter belongs to a complete metric space or a topological space. By using the theory of Baire category and continuous operators on the Hausdorff sub-norm space, we establish the resudual density continuity of a family of pullback random attractors as a map from the parametered space into the Hausdorff sub-norm space. We aslso established the probabilistic continuity and residual continuity of a pullback random attractor depended on time-sample. Stochastic g-Navier-Stokes equation and random fractional delayed FitzHugh-Nagumo equation driven by nonlinear Wong-Zakai noise are applied.
