Abstract

We discuss various issues related to the finite-dimensionality of the asymptotic dynamics of solutions of parabolic equations. In particular, we study the regularity of the vector field on the global attractor associated with these equations. We show that certain dissipative partial differential equations possess a linear term that is log-Lipschitz continuous on the attractor. We then prove that this property implies that the associated global attractor \mathcal A lies within a small neighbourhood of a smooth manifold, given as a Lipschitz graph over a finite number of Fourier modes. Consequently, the global attractor \mathcal A has zero Lipschitz deviation and, therefore, there are linear maps L into finite-dimensional spaces, whose inverses restricted to L\mathcal A are Hölder continuous with an exponent arbitrarily close to one.
