In this work we study the problem of existence of non-constant stable equilibria to some parabolic systems. Specifically, the Ginzburg-Landau system, the Landau-Lifshitz system and systems with skew-gradient structure. In all cases, we note that the geometry of the domain has a fundamental role in the problem above: if the domain has a smooth boundary and is convex, then there are no non-constant stable equilibrium solutions, that is, every non-constant equilibrium is unstable.
