WebWe study fuzzy relations that satisfy the functionality property and that their membership functions can be partial functions. Such fuzzy relations are called partial fuzzy relations, and the variable-domain fuzzy set theory is a framework that provides powerful tools for handling these objects.

Let X \subset \mathbb {R} X ⊂ R. A subset S \subset X S ⊂X is called dense in X X if any real number can be arbitrarily well-approximated by elements of S S. For example, the rational numbers \mathbb {Q} Q are dense in \mathbb {R} R, since every real number has rational numbers that are arbitrarily close to it.
