an unbounded domain are considered. Our aim is to study the long‐time behavior of
parabolic systems for which the nonlinearity depends explicitly on the gradient of the
unknown functions. To this end we give a systematic study of given parabolic systems and
their attractors in weighted Sobolev spaces. Dependence of the Hausdorff dimension of
attractors on the weight of the Sobolev spaces is considered.© 2001 John Wiley & Sons, Inc.
