Pullback attractor of a nonautonomous fourth-order parabolic equation modeling epitaxial thin film growth

Abstract

We study a nonautonomous fourth-order parabolic equation modeling epitaxial thin film growth. It is shown that a pullback attractor of the model exists when the external force has exponential growth.
