摘要
First we establish some necessary and sufficient conditions for the existence of exponential attractors by using omega-limit compactness and a measure of non-compactness. Then we provide a new method for proving the existence of exponential attractors. We prove the existence of exponential attractors for reaction-diffusion equations and 2D Navier-Stokes equations as simple applications. (c) 2012 Elsevier Ltd. All rights reserved.
