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
