,ℝ-Tree Actions are Not Determined by the Translation Lengths of Finitely Many Elements, Hom(.(2, ℂ)) is determined up to conjugation in .(2,ℂ) by the traces of a finite set of elements of .. (See, for example, [.].) The purpose of this paper is to show that the analogue of this basic fact is not true for translation length functions of actions on ℝ-trees.

Evaluating Business and Industry Trainingcial tree, the branching occurs at a discrete set of points, namely, the vertices, whereas in an ℝ-tree, there is no restriction on where branching may occur. The notion of ℝ-tree arose indirectly in the work of Lyndon [.]and Chiswell [.]concerning Lyndon length functions. The first definition was given by Tits in [.].
