For this purpose, a fuzzy norm on $C\left (X, Y \right )$ and its fuzzy dual space and also theĀ  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.}, keywords = {Fuzzy best Simultaneous approximation,Fuzzy subgradient,Fuzzy dual space,Dual seminorm}, url = {https://scma.maragheh.ac.ir/article_34488.html}, eprint = {https://scma.maragheh.ac.ir/article_34488_9c921f0195723c22bf32660b63754739.pdf} }
