Kalina, Martin Derivatives of fuzzy functions and fuzzy derivatives. (English) Zbl 0951.26015 Tatra Mt. Math. Publ. 12, 27-34 (1997). Summary: The paper presents one of the possible approaches to derivatives of fuzzy functions and to fuzzy derivatives. The author distinguishes among three different types of vagueness (fuzziness) and also among three different types of (fuzzy) derivatives. Finally, some applications to fixed points are stated.
