%0 Journal Article %T Linearizability of Non-expansive Semigroup Actions on Metric Spaces %A Lutz Schr£żder %J Mathematics %D 2006 %I arXiv %R 10.1016/j.topol.2007.04.022 %X We show that a non-expansive action of a topological semigroup S on a metric space X is linearizable iff its orbits are bounded. The crucial point here is to prove that X can be extended by adding a fixed point of S, thus allowing application of a semigroup version of the Arens-Eells linearization, iff the orbits of S in X are bounded. %U http://arxiv.org/abs/math/0612553v2
