Abstract :
Fuzzy best simultaneous approximation of a finite number of functions is considered. For this purpose, a fuzzy norm on C(X,Y) and its fuzzy dual space and also the set of subgradients of a fuzzy norm are introduced. Necessary case of a proved theorem about characterization of simultaneous approximation will be extended to the fuzzy case.
