Abstract
This note discusses some aspects of the asymptotic behaviour of nonexpansive maps. Using metric functionals, we make a connection to the invariant subspace problem and prove a new result for nonexpansive maps of ℓ1. We also point out some inaccurate assertions appearing in the literature on this topic.
