Abstract:
We show that, for a semilinear parabolic equation on the real line satisfying a dissipativity condition, global attractors of time-space discretizations converge (with respect to the Hausdorff semi-distance) to the attractor of the continuous system as the discretization steps tend to zero. The attractors considered correspond to pairs of function spaces (in the sense of Babin–Vishik) with weighted and locally uniform norms (taken from Mielke–Schneider) used for both the continuous and discrete systems.
