Abstract:
The qualitative behavior of solutions to a modified Kelvin–Voigt model is studied. An approximation of this model is considered, and the existence of a minimal trajectory attractor and a global attractor for both the model and its approximation is proved. Next, the trajectory and global attractors of the approximation are shown to converge to the trajectory and global attractors of the original model in the sense of the Hausdorff semidistance in corresponding spaces as the approximation parameter tends to zero.
