WebIn the fuzzy case, a context is a tuple (X, Y, L, R), where X and Y are non-empty sets, L is a lattice, and R: X × Y → L is an L-fuzzy relation. Fuzzy concepts in this fuzzy context are pairs (A, B), where A and B are L-fuzzy subsets of the sets X and Y, respectively, which are interrelated in a way, regarding the relation in the crisp case ...

The set of all ordered pair (a,b), where a ∈ A and b ∈ B, is called the Cartesian product of A and B, and is denoted by A × B. For each set A, there exists a set B whose members are subsets of A. We call B the power set of A and write B = P(A). Note that P(∅) is the singleton {∅}. §2. Mappings WebIn set theory, the cartesian product of two sets is the product of two non-empty sets in an ordered way. The Cartesian product comprises two words – Cartesian and product. The word Cartesian is named after the French mathematician and philosopher René Descartes (1596-1650).
