The relationship between symmetry and dimensions of approximate inertial manifolds is established. We demonstrate that symmetry can reduce the dimensions of an approximate inertial manifold. Applications for concrete evolution equations are given. eng restricted access Reduction of dimension of approximate intertial manifolds by symmetry journal article
