Uniform exponential attractors for a singularly perturbed damped wave equation. (English) Zbl 1060.35011
The goal of this paper is to extend the construction of continuous exponential attractors (without time shifts) to singularly perturbed damped wave equations. The difficulty here is based on the fact that the phase spaces for the perturbed and unperturbed equations are not the same (the limit equation being a (parabolic) reaction-diffusion equation).
