Abstract

This paper deals with the best approximation for fuzzy valued functions using Chebyshev nodes. We prove a result on the best near-minimax approximation in the fuzzy sense. As an application, Runge’s phenomenon is fuzzified in two different cases, i.e. the best approximation and the best near-minimax approximation.
