F. Balibrea et J. Valero, ESTIMATES OF DIMENSION OF ATTRACTORS OF REACTION-DIFFUSION EQUATIONS IN THE NON-DIFFERENTIABLE CASE, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 325(7), 1997, pp. 759-764
We improve a general theorem of O. A. Ladyzhenskaya on the dimension o
f compact invariant sets in Hilbert spaces. and use it to prove that t
he dimension of global compact attractors of some differential inclusi
ons and reaction-diffusion equations are finite.
