Almost periodic fuzzy-number-valued functions. (English) Zbl 1053.42015

Summary: We develop a theory of almost periodic fuzzy functions, i.e., of the almost periodic functions of a real variable with fuzzy real numbers as values. Although the class of fuzzy real numbers does not form a linear normed space, the majority of the main properties of almost periodic functions with values in Banach spaces are extended to this case. Applications to fuzzy differential equations and to (fuzzy) dynamical systems are given.
