INVARIANT MEANS AND FIXED POINT PROPERTIES OF SEMIGROUP OF NONEXPANSIVE MAPPINGS
Anthony To‐Ming Lau · Taiwanese Journal of Mathematics · 2008
This paper outlines some of my recent joint works with Q. Takahashi on fixed point properties or ergodic properties for semigroup of nonexpansive mappings on closed convex subsets of a Banach space and their relationship with existence of left invariant mean on certain subspaces of bounded realvalued functions on the semigroup.
