Title: Continuity of attractors for a reaction-diffusion problem with respect to variations of the domain Authors: Luiz A. F. de Oliveira (Univ. de Sao Paulo, Brazil) Antonio L. Pereira (Univ. de Sao Paulo, Brazil) Marcone C. Pereira (Univ. de Sao Paulo, Brazil) Abstract: We show that for a class of dissipative semilinear parabolic problems, the global attractor varies continuously (upper and lower semi-continuously) with respect to perturbations of the spatial domain.
