Abstract

We present basic properties of the operation of sup-T composition of partial fuzzy relations, i.e., fuzzy relations defined on arbitrary subsets of the Cartesian square of the referential set. We show that for partial fuzzy relations, these properties are fairly similar to those for totally defined fuzzy relations. Furthermore, we show that the studied elementary properties of sup-T composition of partial fuzzy relations carry over to several composition-related operations on partial fuzzy relations and partial fuzzy sets, including the operations of image, preimage, and Cartesian product.
