On the asymptotic behavior of the solutions for a class of thermoelastic system.

Abstract

In this work we prove the existence and regularity of the global attractors and the pullback attractors for a class of autonomous and non-autonomous thermoelastic systems, respectively, with vanishing mean value for temperature in a bounded domain with sufficiently smooth boundary in Rn with n ě 2. Moreover, we prove the upper semicontinuity of the attractors with respect to the diffusion coefficients.
