WebMar 24, 2024 · A relation is any subset of a Cartesian product. For instance, a subset of A×B, called a "binary relation from A to B," is a collection of ordered pairs (a,b) with first components from A and second components from B, and, in particular, a subset of A×A is called a "relation on A." For a binary relation R, one often writes aRb to mean that (a,b) is … WebMar 15, 2015 · Relations in Discrete Math 1. RELATIONS PearlRoseCajenta REPORTER 2. What is a 'relation'?

Web5 Answers. Try this: consider a relation to be antisymmetric, UNLESS there exists a counterexample: unless there exists ( a, b) ∈ R and ( b, a) ∈ R, AND a ≠ b. Since no such counterexample exists in for your relation, it is trivially true that the relation is antisymmetric. Another way to put this is as follows: a relation is NOT ...
