Existence of Global Attractor for a Modified Swift - Hohenberg Equation

This study mainly aims to explore the existence of global attractor for a modified Swift-Hohenberg equation. The method we use was the classical existence theorem of global attractors and the theory of semigroups. Use this method we prove that the equation exist a global attractor in H12 space, and the global attractor attracts whatever bounded subset of H12 in the H12 -norm.
