Fuzzy Cartesian product, fuzzy relations and fuzzy functions
A new approach to Cartesian product, relations and functions in fuzzy set theory is established. A concept of fuzzy Cartesian product is introduced. A fuzzy relation is then defined as a subset of the fuzzy Cartesian product analogously to the crip case. Finally, the notion of a fuzzy function is introduced as a special type of fuzzy relations. This fuzzy function generalizes Zadeh's definition of functions in the fuzzy context.
