چکیده
This paper sets out a theoretical framework for approximating the attractor si of a semigroup S{t) defined on a Banach space A" by a q-step semidiscretization in time with constant steplength k . Using the one-step theory of Hale, Lin and Raugel, sufficient conditions are established for the existence of a family of attractors {$fk } c Xq , for the discrete semigroups S£ defined by the numerical method. The convergence properties of this family are also considered. Full details of the theory are exemplified in the context of strictly /f(a)-stable linear multistep approximations of an abstract dissipative sectorial evolution equation.

متن کاملupper semicontinuity of attractors for small random perturbations of dynamical systems
The relationship between random attractors and global attractors for dynamical systems is studied. If a partial differential equation is perturbed by an −small random term and certain hypotheses are satisfied, the upper semicontinuity of the random attractors is obtained as goes to zero. The results are applied to the Navier-Stokes equations and a problem of reaction-diffusion type, both pertur...
متن کاملUpper Semicontinuity of Pullback Attractors for the 3D Nonautonomous Benjamin-Bona-Mahony Equations
We will study the upper semicontinuity of pullback attractors for the 3D nonautonomouss Benjamin-Bona-Mahony equations with external force perturbation terms. Under some regular assumptions, we can prove the pullback attractors A(ε)(t) of equation, u(t)-Δu(t)-νΔu+∇·(-->)F(u)=εg(x,t), x ∈ Ω, converge to the global attractor A of the above-mentioned equation with ε = 0 for any t ∈ R.
متن کاملUpper semicontinuity of global attractors for damped wave equations
Abstract: We provide a new proof of the upper-semicontinuity property for the global attractors admitted by the solution operators associated with some strongly damped wave equations. In particular, we demonstrate an explicit control over semidistances between trajectories in the weak energy phase space in terms of the perturbation parameter. This result strengthens the recent work by Y. Wang a...
