Fuzzy smoothness and sequences of fuzzy smooth functions. (English) Zbl 0955.26011
Summary: This paper is a continuation of the work [M. Kalina, Tatra Mt. Math. Publ. 14, 153-159 (1998; Zbl 0944.26030)]. It further investigates fuzzy smoothness of fuzzy continuous, but crisp, functions. Finally, sequences of fuzzy smooth functions and their sums are considered.
