The Steiner Ratio and the Embedding of Spaces
Assume that we know the Steiner ratio of a metric space (X′, ρ′) and we have that (X′, ρ′) is a subspace of (X, ρ). Then m(X, ρ) must be less or equal than m(X′, ρ′). This observation is the core of the present chapter, but in a less weak form: We consider functions which map the space (X′, ρ′) into (X, ρ) which preserve the distance between points.
