報告題目:Continuity ofpullback random attractors for nonautonomous cocycles

報告摘要: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.
