Chebyshev approximation by ordinary rational functions with respect to a vanishing weight function is considered. A best approximation is characterized by alternation and is unique but may not exist. The problem arises in Kuki’s technique for rational approximation with interpolation at zero and with Williams’ interpolating rationals.
