Title: Large time behavior of a Cahn-Hilliard-Boussinesq system on a bounded domain Author: Kun Zhao (Ohio State Univ., Columbus, OH, USA) Abstract: We study the asymptotic behavior of classical solutions to an initial-boundary value problem (IBVP) for a coupled Cahn-Hilliard-Boussinesq system on bounded domains with large initial data. A sufficient condition is established under which the solutions decay exponentially to constant states as time approaches infinity. Submitted April 11, 2010. Published April 06, 2011.
