Abstract

Several approaches to define the differential of fuzzy-valued mappings can be found in the literature. In this paper we introduce a new concept of differential of a fuzzy-valued mapping, which is based on the notion of differential of the support function associated with such a mapping. Properties of the new concept, as well as the relation between it and previous approaches are also analyzed in detail.
