Comments on the cosmic convergence of nonexpansive maps
Armando W. Gutiérrez, Anders Karlsson · Journal of Fixed Point Theory and Applications · 2021
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 $$\ell ^{1}$$ ℓ 1 . We also point out some inaccurate assertions appearing in the literature on this topic.
