Abstract

We prove an estimation of the Kolmogorov $\varepsilon$ -entropy in $H$ of the unitary ball in the space $V$ , where $H$ is a Hilbert space and $V$ is a Sobolev-like subspace of $H$ . Then, by means of Zelik's result [7], an estimate of the fractal dimension of the attractors of some nonlinear parabolic equations is established.
