Anastassiou, George A.; Gal, Sorin G. On a fuzzy trigonometric approximation theorem of Weierstrass-type. (English) Zbl 1004.42005 J. Fuzzy Math. 9, No. 3, 701-708 (2001). Summary: We prove that any \(2\pi\)-periodic fuzzy continuous function from \(\mathbb{R}\) to the fuzzy number space \(\mathbb{R}_{\mathcal F}\) can be uniformly approximated by some fuzzy trigonometric polynomials.
