Abstract: Our aim in this article is to study the long time behavior, in terms of finite-dimensional attractors, of a coupled Allen–Cahn/Cahn–Hilliard system. In particular, we prove the existence of an exponential attractor and, as a consequence, the existence of the global attractor with finite fractal dimension.

Keywords: Allen–Cahn/Cahn–Hilliard system, global attractor, exponential attractor, fractal dimension
