WebIt is immediate that δ dF(P,P) = 0, δ dF(P,Q) = δ dF(Q,P); furthermore, one can check that δ dF(P,Q) = 0 implies P = Q and that δ dF(P,Q) ≤ δ dF(P,R) + δ dF(R,Q). We thus have the following. Proposition 1 δ dF defines a metric on the set of polygonal curves. The relationship of δ dF to δ F is captured by the following two lemmata, from which we ...
