Abstract
A spatially two-dimensional sixth order PDE describing the evolution of a growing crystalline surface h(x, y, t) that undergoes faceting is considered with periodic boundary conditions, as well as its reduced one-dimensional version. These equations are expressed in terms of the slopes (Formula presented.) and (Formula presented.) to establish the existence of global, connected attractors for both equations. Since unique solutions are guaranteed for initial conditions in (Formula presented.), we consider the solution operator (Formula presented.), to gain our results. We prove the necessary continuity, dissipation and compactness properties.
