WebReflexive Relation Characteristics. Anti-reflexive: If the elements of a set do not relate to itself, then it is irreflexive or anti-reflexive. Quasi-reflexive: If each element that is related to some element is also related to itself, such that relation ~ on a set A is stated formally: ∀ a, b ∈ A: a ~ b ⇒ (a ~ a ∧ b ~ b). Co-reflexive: A relation ~ (similar to) is co-reflexive for all ... WebIn discrete mathematics, the relation can be described as a collection of ordered pairs. It is used to relate an object from one set to the other set, and the sets must be non-empty. The relation can contain two or more than two sets. Get Started. Relations ...
