The differential and subdifferential for fuzzy mappings based on the generalized difference of n-cell fuzzy-numbers.

We use the concept of generalized difference for fuzzy n-cell numbers which is presented in this paper to introduce and study the differential and gradient of fuzzy n-cell mappings. At the same time, some connections between gradient, boundary-function-wise gradient and level-wise gradient of fuzzy n-cell mappings are established. Furthermore, the subdifferential for fuzzy n-cell mappings based on the ordering ...c is discussed. [ABSTRACT FROM AUTHOR]
