Abstract:
In this article, we construct robust (i.e. lower and upper
semicontinuous) exponential attractors for singularly
perturbed phase-field type equations. Moreover, we obtain
estimates for the symmetric distance between these exponential
attractors and that of the limit Cahn-Hilliard equation
in terms of the perturbation parameter. We can note that the
continuity is obtained without time shifts as it is the case
in previous results.
