|Title:||Global attractor and omega-limit sets structure for a phase-field model of thermal alloys|
|Abstract:||In this paper, the existence of weak solutions is established for a phase-field model of thermal alloys supplemented with Dirichlet boundary conditions. After that, the existence of global attractors for the associated multi-valued dynamical systems is proved, and the relationship among these sets is established. Finally, we provide a more detailed description of the asymptotic behaviour of solutions via the omega-limit sets. Namely, we obtain a characterization - through the natural stationary system associated to the model - of the elements belonging to the omega-limit sets under suitable assumptions.
