In contrast to the complex case, the best Chebyshev approximation with respect to a finite-dimensional Haar subspace \(V \subset C(Q)\) ( \(Q\) compact) is always strongly unique if all functions are real valued. However, strong uniqueness still holds for complex valued functions \(f\) with a so-cal

Chebyshev Approximation of Plane Curves

Given a parametric plane curve \(\mathbf{p}\) and any BΓ©zier curve \(\mathbf{q}\) of degree \(n\) such that \(\mathbf{p}\) and \(q\) have contact of order \(k\) at the common end points, we use the normal vector field of \(\mathbf{p}\) to measure the distance of corresponding points of \(\mathbf{p}\
